Add Addon-domain to package in WHM.

[MarcelB]

As reseller, not server owner/root.

In WHM I've got a package with 1 domain, now a client wants a second and maybe third domain as addons.

How do I do this in WHM, do I have to create a new package with 2 domains and a new package with three domains etc.

If I upgrade the excisting package all clients will have 2nd domain and that's not supposed to happen.

What's the best way to deal with this.
