I have a pre-existing billing account for an earlier project, that works fine.
How can I associate a new project with that same account?
In the Google Developer Console, if I select the new project and try to enable billing it gives me the forms to create a new billing account. I did not find a way to associate the project's billing to the existing account.
If I look at the existing billing account I can see my earlier project in the list of projects but have found no way add a new project to the account.
