How to stop user(s) requesting permission to create applications billed to the account

I understand and share your concern. However, I think Quick Base doesn't like you controlling that. They want people to create applications and if they can't keep bombarding you with those requests until you relent. I have been asking QuickBase to do this for several years as well and I am interested in seeing their response now, especially because it is not an Intuit company anymore. Fingers crossed!
