How to list all matching cells, Compare tool

I will include the files so that you can see what I am saying. These are just dummy files but you should be able to tell what I am looking for.

The files that I am copying from are the Facility Export and DocAttributes files. I am doing the comparison in the FINALTEST file.

As you can see the same value is listed in A3 and A4 (in FINALTEST), when that same value is searched for (because its in B6), it only finds the first instance of that entry (in A3). A4 is never mentioned even though that value clearly matches the value in B6.

I would like C6 (right now it shows A3) to show both cells, as in reading something along the line of A3, A4.

If you need any more info please let me know and I would be glad to include it.
