Format variables in merge export --output-file

[Rankarusu]

Expected Behavior

It would be nice if I had access to variables for timestamp, space-id, source-environment-id and target-environment-id inside merge export --output-file so I dont have to query all that data myself when I want to save my generated migrations to a different path. I'm thinking of something that date libraries usually do where you can use something like %d. %m. %Y and these variables get replaced by the corresponding data.

Actual Behavior

I can either use the default path and file name or need to specify a full path. When I would want to add the space Id to the file name, I would get it beforehand.

Possible Solution

see expected behavior

Context

I'm trying to build a migration script for ci/cd-pipeline. We have multiple spaces and environments. As there is no information written about those inside the migration file, I would like to extract that from the file name.
