I do the same thing but in a low tech way. I write down the 25 guys I want with pencil and paper and make sure they are less than 80m. If someone takes one of my guys he gets erased and I look for a replacement which could give me more money to upgrade at another unpicked position. I've been pretty lucky as only one of my projected players has been erased so far!
That reminds me of the Schwarzenegger movie THE ERASER.
