Hi Amy,
One pretty simple solution would be to create a formula-checkbox that checks to see if the multi-select field is empty. I used the following field to check...
If(ToText([Multiselect Field])<>"", true, false)
Then you could add this checkbox to the filters of the report. You could also make it a report formula if you would like. I hope this helps! Please let me know if you have any questions or I am misunderstanding the issue!
