Multiple user ID/Email

Hi,

First of all thanks for the great plugin. I was wondering if there was a way to show a logged in user tickets from a selection of other users as well. For example, we want person A to also see tickets from person C and E, but not B and D. The reason for this is person A, C and E all belong to the same company. In terms of shortcode, it would be some like user_id=”A,C,E”. Thanks for your time.
