Active Lists Based of Rolling 30 day or Time Parameter Window

HubSpot Ideas

It would be amazing if an active list could be created with time parameter window.

My example is I have a large growing active list of contacts. I would like to create a second active list with the base of that group of contacts with a window ONLY looking at a last 30 day window of users hitting that base contact list. So for example in the new Active List, as of today I would only be able to see users back to April 7, 2021. Tomorrow I would only have contacts that go back to April 8, 2021.

This would be very useful. We are trying to segment by a 30-60 day since last form submission. This would be ideal
