Multiple SSL certs, one virtual server. Choose based on URL?

We have a setup where we have a master site that many companies point to and based on the URL the branding will be set but the core function is the same. So master site is say www.master.com and we want www.company1.com and www.company2.com to go to the same external IP of www.master.com. That will then go to same pool for all URL's and the web servers based off the URL will brand the site as needed. However these are https services so each site needs its own cert. I can not see how to do this. I know I can use an iRule to set the pool based on the URI but the SSL profile is associated with the virtual server. Any thoughts on how I can accomplish this?
