How do we bill projects separately and/or transfer of resources to different teams or accounts?

I have what I expect is a common problem:- the need to separate billing for different projects, even though I am the main technical administrator and want to maintain some oversight. This can happen, e.g.: (1) if you have private and work projects but don’t want them all billed on the same credit card, (2) you develop an app in house for speed but then want to be able transfer ownership (and particularly billing) to a customer or third party, (3) you have multiple different customers or friends you are helping and you don’t want all the bills to go through one card. Etc etc.

Some time back I requested support from DO on the topic and was advised the best way to separate billing was to create new Teams which could be billed using different credit cards.

I duly tried this. But it turns out that there is no way to actually transfer running instances of apps, databases or other resources from one team to another. The only option seems to set up everything from scratch. This is hardly convenient when we are talking about running apps and databases.

Am I missing something? There seem to be lots of requests for separate billing features or ability to transfer resources on ideas.digitalocean.com but no movement from DO, as far as I can tell.
