Sub-Domain DB

Hi,

I wanted to find out, in the Server Template - Default Setting - MySQL database - Default database name - it has ${PREFIX}. This means it is taking the first part of the domain?

If so, could i use for the sub domain ${DOM} so it can create the whole sub-domain name in the DB?, like this Server Template - Settings For Sub-Servers - MySQL database - Default database name - Template - ${DOM}

In the DB it will be like demo.domain.com, now its just creating demo DB.

Thanks
