Allow customers to customize auto top-up

If I understood the documentation correctly, there’s no way for user to disable auto top-up themselves.

I’d like to build a feature that allows customer to set up auto-top setting themselves.
I want my users to be able to:

• make one time purchase to buy in-app credits

• set up auto-top settings so purchases are made automatically when user is low on in-app credits.

Right now the only solution I see is to have two separate products - one for auto top-up and one for manual purchases.
