Link single contact to multiple projects

Is there a way to link a single contact to multiple projects?  

When I attempted to select more than one project on a contact in Outlook 2010, I was not able to do so. 

I tried holding down the shift key and then the control key when selecting a project, but I was not able to select more than one project for a contact. 

Thanks for your help.

Categories are the key

Ed - thanks for the question.

The answer is Yes and No.

Our tool doesn't support (natively) the ability to choose more than one project for a contact.  However, since the projects are stored per object in the categories field, it is possible to assign more than one category to an object using Outlook's native capability. 

For example, you could open a contact, use the Categories button to assign multiple categories (in this case multiple projects since they're listed in the Master Category List (MCL)).  Then in Project Explorer, that contact will show up underneath each referenced project.

Hope that helps.

Thx
