Assign multiple records to a single graphic in Visio (Or SharePoint 2013 in Office 365)

Hello,

I would like to make a live seating chart for an event.  I am pulling data from a SharePoint 2013 list that has names and table numbers (and other stuff).  There will be 10 names per table.  Each name is a record, not each table number.  10 names will have the same table number.  I can only see where Visio lets me attach one record to a graphic.  I can automatically link Tbl# (in my list) toTable_No in the graphic but it will only pick up the first entry, not all 10.  Is there a way to tell Visio to look at the list, and whereTbl# equals Table_No attach the first and last name from all 10 records to the graphic?  I want it to be dynamic so when they edit the list, the tables change accordingly.

Maybe there is an app for that in SharePoint?  I am working on Office 365 SharePoint.

Thank you for any assistance.
