Multiple Templates (hosting plans) per client

Hi all,

I've just started to look at using ispconfig 3, seems great so far.

I want to use it for some existing hosting clients we have.
But how do we handle multiple hosting plans per user/client?

e.g. we have 2 hosting plans:
- Plan A: 1 site, 50mb space
- Plan B: 1 site, 100mb space, 1 mysql db.

and 2 customers:
- Customer 1
- Customer 2

Customer 1 has 2 web sites
- domain1.com: Plan A
- domain2.com: Plan A

Customer 2 has 2 web sites
- domain3.com: Plan A
- domain4.com: Plan B

So each customer can have multiple plans.
However in ISPconfig 3, I can create clients ok, create the templates (hosting plans), but it appears only 1 template can be applied to a client.

How can I let 1 customer (client) log into the CP with 1 username, and have multiple hosting plans (templates)?

Thanks
Mike
