You can just type the names in cells in the lefthand column of a spreadsheet, then do save as file type .txt
Then point the trigger to that file you have saved.
so for example players_1.txt then you can save other selections, in other files and always save the file in that name for the day. If you check the box Reread File in the condition it will re-look at the file every time it runs so you can even re-edit the file of names during play, without touching MF pro. (I do find this a bit dodgy sometimes and cannot get it to start firing on a new days selections without closing the platform and restarting it.)
