Ruby on Rails cache: Is it possible to increase the expiration time for a cache fragment during the execution time?

I am using Ruby on Rails 3 and I would like to increase the expiration time for a cache key during the execution time. I use memcached.

For example, I have 

Rails.cache.write("key_test", "value_test", :expires_in => 10.seconds)

so that the key_test will expire in 10 seconds. In order to make available that key value for longer, what I can do? Is it possible to increase only the expires_in without to set again the value_test?

The following code doesn't work, but maybe I have to do something like this:

Rails.cache.write("key_test", :expires_in => 10.seconds)

This will work:

Rails.cache.write('key_test', Rails.cache.read('key_test'), :expires_in => 10.seconds)
