Selecting multiple items in the same category when a user is finding matches

[KenChenRyan]

What problem does this feature address?

Being able to select multiple items from the same category (whether it's Have, Want, or From) when finding matches. For example matching with users that have more then one specific game you desire.

Describe a solution

Either letting a user selecting multiple items via shift or command (on a Mac)/ctrl (on a Windows). Or having a plus button next to each item, that when clicked on lets the user make an additional selection in the category of their choice.
