Desktop Integration for ProjectLink

All -

I am evaluating a copy of Microsoft Project 2013 in the hopes that it will ease the transition to ProjectLink (WC10.1) for my users.  I have successfully exported a project from ProjectLink to Project.  Is Desktop Integration required to modify it and upload it back to Project?  If so, how do I set that up?

Maybe this should go to PTC Support, but I thought I'd give the Community a try...

Thanks in advance -
