How can we improve WHMCS?

https://www.pivotaltracker.com is an agile project planning tool. Currently we use the whmcs project tool for small projects but we use pivotal tracker for larger projects.

We would like to have a basic integration into support tickets. Right we add a link to whmcs ticket in pivotal tracker story and vice versa. It would be nice to have a way to automate this in one direction or the other. It would also be nice to have Pivotal tracker story status indicators in the whmcs ticket.
