Subdomain with an existing mountpoint

[Claus]

Hi,

i need to create an subdomain which has the same mount point like the domain itself.
Actually, this is not possible at the frontend. -> I created a ticket for this a few minutes before.

Because this is a very important feature for me, can anyone tell me, if I can change the mountpoint manually after the creation? And if so, how it works ( which files need to be updated, which point of the ISPCP-Database) ?

Thanx a lot.

Regards, Claus
