Migrating from Cpanel and SSL

Hi,

I am trying to migrate my site from cpanel to Interworx. Everything seems to be working fine except SSL. My site consists of 2 components:

mysite.com
and
forum.mysite.com

I have a SSL certificate for each one. In CPanel adding the 2 certificates is very easy.

In Siteworx, I can add a private key and certificate and it works fine for 1. However there is no option to add 2 keys and 2 certificates. I have tried adding them both on the add SSL private key and SSL Certificate fields but it only picks up one. Any advice?

Thank you
