Allowing automation settings (setting messaging 1-way or 2-way options delivering content, adding to groups) would greatly reduce the amount of manual changes we have to make when someone purchases an add-on.

For example: I have a core product which does not include 2-way messaging.

When they add on a certain add-on product, 2-way messaging is one of the perks I include with the add on.

I currently have to manually go in and change this for each person, instead of it being automated like a normal product.
