Smart keep strategy

[Kenya-West]

I want to keep last 5 snapshots from everyday backup, the weekly 3 snapshots, 3 monthly ones.

I imagine like the app does everyday backup and automatically removes old copies between weeks and months, so it would keep the list of snapshots like this:

• Last 5 days;
• then 3 snapshots a week, two, three ago;
• then 3 snapshots a month, two, three ago.

- so, 11 in total, no more. Every snapshot between these dates will be automatically deleted.

Is that possible?
