Check matches 11 transactions

We just wrote 13 checks to a group of musicians. 11 checks were for $300 and 2 were for $400. Check matching is finding 11 for each of the $300 checks and 2 matches for the $400 checks. When the checks were written and entered into QuickBooks we attached files unique to each Musician to document the authorized payment. Now I need to match the downloaded checks to the correct QuickBooks check. Not enough information in check matching to do that. How do I do distinguish one check from another when I see all 11 as matching?
