Retain more remote backups than local

This seems like an obvious feature but I can’t seem to find it in the UI.

My local disk does not have a lot of space for backups but I do have it set up to backup to my NAS as well.

The problem is that I can’t tell it to keep more NAS backups (e.g. a month) than local backups (e.g. 2 days)

It seems like it only has one global cleanup option that applies to all backup locations… So the number of NAS backups I can store is limited by my tiny local disk.

Does this feature exist somewhere and I’m just missing it?
