When your recording the match just do ''/clear'' then ''/pb_plist'' or/and ''/guids'' after you done that do ''/condump startmatch.txt''. Their guids will be stored in your demo plus als in your et folder as .txt file. When ever someone reconnects or connect do it again but name the condump file something else of course.
Now go to your etpro folder and search the .txt files, tada how hard can that be.
you can even bind it in 1 key
