The answer is the report designer uses the table names behind the scenes so if you're pulling from different tables with the same field name multiselects do NOT appear. The work around is to modify the domain and alias the table name... I named them both TABLE since I'm so creative. This allows me to trigger changes on multiple reports in a dhasboard with a single update value. I can also add criteria that are specific to one report or another. Hoping to get more support on the other questions I posted and to not have to solve all my issues myself. Not off to a good start.
