Parse hierarchical text output with textfsm

I'm having some trouble to parse hierarchical data from an equipment with textfsm.

The data is something similar to that:

pcc-filter-base-name : P2P-BASE
filter = 1337x
filter-state = enabled
flow-inactivity-time = 0
flow-initiation = uplink
l7-uri = 1337x:
precedence = 1
protocol-id = 0

filter = abc
filter-state = enabled
flow-inactivity-time = 0
flow-initiation = uplink
l7-uri = abc:
precedence = 2
protocol-id = 0

filter = adc
filter-state = enabled
flow-inactivity-time = 0
flow-initiation = uplink
l7-uri = adc:
precedence = 3
protocol-id = 0

pcc-filter-base-name : FACEBOOK_FLEX-BASE
filter = IP_NET_1
destination-address = 157.240.24.32/29
destination-port-list = 80,443
filter-state = enabled
flow-inactivity-time = 0
flow-initiation = uplink
precedence = 1
protocol-id = 0

filter = IP_NET_2
destination-address = 157.240.25.32/29
destination-port-list = 80,443
filter-state = enabled
flow-inactivity-time = 0
flow-initiation = uplink
precedence = 2
protocol-id = 0

filter = IP_NET_3
destination-address = 157.240.26.32/29
destination-port-list = 80,443
filter-state = enabled
flow-inactivity-time = 0
flow-initiation = uplink
precedence = 3
protocol-id = 0

I was trying to parse it with this template:

Value Filldown filter_base_name (\S+)
Value Required filter (\S+)
Value filter_state (\S+)
Value flow_inactivity_time (\S+)
Value flow_initiation (\S+)
Value l7_uri (\S+)
Value Required precedence (\S+)
Value protocol_id (\S+)
Value destination_address (\S+)
Value destination_port_list (\S+)


Start
 ^pcc-filter-base-name : ${filter_base_name} -> Filter

Filter
 ^filter = ${filter}
 ^filter-state = ${filter_state}
 ^flow-inactivity-time = ${flow_inactivity_time}
 ^flow-initiation = ${flow_initiation}
 ^l7-uri = ${l7_uri}
 ^precedence = ${precedence}
 ^protocol-id = ${protocol_id}
 ^destination-address = ${destination_address}
 ^destination-port-list = ${destination_port_list}
 ^pcc-filter-base-name : ${filter_base_name} -> Record Start

However this is far away from the result I was expecting, which isto gather all filters from each filter-base.

I've tried several approaches so far, but I have no idea of what I'm doing, maybe textfsm is not the right tool for that job?

Thanks in advance for the help.

Seems like I've only needed to post the question to get an answer by myself...

Value Filldown filter_base_name (\S+)
Value Required filter (\S+)
Value filter_state (\S+)
Value flow_inactivity_time (\S+)
Value flow_initiation (\S+)
Value l7_uri (\S+)
Value Required precedence (\S+)
Value protocol_id (\S+)
Value destination_address (\S+)
Value destination_port_list (\S+)


Start
 ^pcc-filter-base-name : ${filter_base_name} -> Next.Record
 ^filter = ${filter}
 ^filter-state = ${filter_state}
 ^flow-inactivity-time = ${flow_inactivity_time}
 ^flow-initiation = ${flow_initiation}
 ^l7-uri = ${l7_uri}
 ^precedence = ${precedence}
 ^protocol-id = ${protocol_id} -> Next.Record
 ^destination-address = ${destination_address}
 ^destination-port-list = ${destination_port_list}
