Short answer is 'Yes'. Extension and Call Group are two separate entities.
We created a template to override the Call Recording, and then every so often go back and re-run it.
For some 'unknown' reason - call recording keeps getting turned off on random staff... and there's nothing in the Audit Log (when that works) that shows it, nor has tech support been able to say what's causing it to get switched off.
Also - if you're using it for trying to go back and review calls in the past - recall that RC doesn't store anything past 6 months. (why 6 months, again - no clue when storage is cheap) You'll need to get a good storage/export service to hold anything longer.
Please remember to look at your local/state laws for regulations on call recording/notification to callers - that's a big deal here in California!
Have fun.
