Autofund Rollover Categories

I enjoy the rollover categories and being able to have them “autofund” so I don’t have to manually go in and add to them. My question is if there is anyway to choose a date? I don’t want them to always autofund from the 1st of the month as that skews my numbers. Many of them I would like to autofund say on the 15th after some income has come in. I understand it may be difficult to allocate an actual amount (especially since this app is designed to have us get away from that mind set) but always having it at the beginning of the month messes with my brain a little too :)
