New databases with user prefix?

[DaSilva]

Is it possible to automatically add an user prefix to every new database that is created by a customer?
Because now after an update from VHCS2 I have many databases with names that I cannot assign to a customer.
As an example:
Customer domain.tld has this database name: "phpbb3"
New databases should be like "{cutomer_id}_phpbb3" ("12_phpbb3" if the customer has "12" as id).
The old databases cannot be changed because it would cause errors I think.
Thanks for help.
