invitees to meeting from a module other than contacts or leads

I’ve built custom modules for clients and referrers. How would I go about modifying the meetings module so that i could include search results from these modules when searching for invitees? Many thanks!

You would need to heavily customize the PHP code. This can not be done out of the box.

Thanks, I had come to that conclusion. Is it only the files SubPanelViewInvitees.html and SubPanelViewInvitees.php or are there others that would require modification? Thanks again.
