I know you can quick select the time when setting up media permissions from 1 hour to 7 days, but there's any way to do that like 1 month or more ahead?

I'm asking it because my fans only can see my feed for a selected period (I set my posts to be displayed from the next month to 6 months ahead depending of the Tier) and I use it for 2 reasons: to avoid my fans to see my all my posts paying cheap AND mainly to avoid all my future content to be leaked someday, as it already happened.

If there's no way to do that, here's my suggestion. I think it would be a great addition and should not be so complicated to implement :) I already do it manually but is a pain in the *ss to calculate it
