I've tried to create a scheduling automation, but I don't think this option exists.
My intention is:
(Trigger) Every day. (Action) Move each card from the SAVED list, with the name ISASI, to the ISASI list on the CAJON board, after 30 days of those cards remaining in the source list (SAVED).
It would be a combination of these two rules.

Action 1 doesn't allow me to choose a time interval that isn't related to the creation or completion date. Action 2 is based on elapsed time.

I don't know if it can be done in any way.
Greetings
