An account opting in for more than 10Apps

Each person on my app has one account, but a person can have many contracts, more than 10.
What’s a good way to increase this?

So far I’m thinking create a general app for that user that holds appId in global state so it can have up to 64. Is this the way to go? Any alternatives?

I missed that info, I don’t need local state. Problem solved. Thank you.
