Filtering on Contents of Concatenated Column

I have a column from a table that comes in as a choice column from SharePoint. I've combined the multiple selections from this column using the concatenate function. But now I would like to filter tables based on the contents of that column. See below for an example. 

I haven't seen anyone else post about being able to do this. It seems like this should be possible. I don't know if a DAX measure would need to be used to make the slicer or determine how projects are shown in the second table. 

Thank you!
