Non Runner Removal

[focusrite]

Hi all, new user looking to place conditional horse win bets using excel through BETDAQ.

Can anyone tell me what happens to non runners / wd horses through the betdaq api? For instance: I place a bet on horse "H" at midday to trigger one minute before the off at 3:15 but at 1pm horse "G" is a non runner. Does horse "H" move up to become horse "G"? I might be betting on 5 runners in a 12 runner race so this could become a complete nightmare.

Also I would like to add some columns in between existing columns to the multiple spreadsheets to customise them for my personal requirements. Is this essentially going to destroy how bet angel connects to this workbook?

Thanks in advance for any replies.
