Convert restId to the entryId with calling translateExchangeIds?

As a followup to Converting restId format type to old Outlook HexEntryId type :
Since user2250152's excellent answer indicates that I have to do some programming myself, I was wondering:

Can I also do the conversion for the restId to the entryId myself?
That would save a call to translateExchangeIds.

Example data from the translateExchangeIds call:

"sourceId": "AAMkADI2ZGIwY2FlLTA1NDQtNGFhYi1hNDJmLWEyMGJhZWU5NmM2YgBGAAAAAACrxyqss0H-T5iGuqwSXncoBwB1kc8DNbIxRK3H-NcbpuL8AAAAAAENAAB1kc8DNbIxRK3H-NcbpuL8AAKHvUXcAAA="
"targetId": "AAAAAKvHKqyzQf9PmIa6rBJedygHAHWRzwM1sjFErcf81xum4vwAAAAAAQ0AAHWRzwM1sjFErcf81xum4vwAAoe9RdwAAA2"

"sourceId": "AAMkADI2ZGIwY2FlLTA1NDQtNGFhYi1hNDJmLWEyMGJhZWU5NmM2YgBGAAAAAACrxyqss0H-T5iGuqwSXncoBwB1kc8DNbIxRK3H-NcbpuL8AAAAAAENAABV1BT8PvI4S78XiwEQP4DVAATuyF7bAAA="

EWS and Graph/rest Id's (which are just a base64URL safe version of the ewsId) contain the EntryId + some flags that tell the backend how to open the item. Microsoft don't document the format because they consider it opaque and subject to change. So you can do it yourself but it won't be supported if you convert both of the values to Hex and work backwards you'll see what i means eg
