User Problem

Our users would like to move cards from list 1 to list 2, based on when the cards were added to list 1. ex: 30 days after being added to list 1.

Suggested Solutions

We have an existing rule like this "Every day, move each card in the list "To Do" with a name starting with "ISI" to list "Doing""

We want to be able to add something like:
"every day, move each card in the list "To Do" with a name starting with "ISI" added more than 30 days from now to the list "Doing".

Current Workarounds

We can add a custom field and move the items based on the date on the custom fields.
