TODO / Flagging Callsigns to check before export

I watched your video with Dave G3LRC and saw the TODO option which is great as I’m dyslexic and often swap two letters around.
Would it be possible to allow me to enter the call but with a ? of ?? after it G1ABC?? and be able to save the call during the pileup but then it prompts me to correct the call when I export?
The todo is a great option but for speed in a pileup a quick way to flag a call would be handy.

The question marks are not a bad idea. Let me see what we can do

Thanks Seb, it’s appreciated.
