How do I move money around in my budget if I overspend in a category?

I’m sure there is info on this but I can’t find it anywhere! I’m new to Tiller and need to know how to easily move money around in my budget when I overspend in a given category. I know I can go back to the Categories sheet and manually edit that but there has got to be a better way. Please advise. This feels like a deal breaker for me.

The Savings Budget template offers something like that. In the end, it’s just adjusting the amounts in the Categories sheet, but it gives a nicer interface/tool to do that.
