Kill offsets!
What have you tried?
I would add a rule to whichever rules file you have created and select 'Cancel All Unmatched Bets On Selection', choose the same selection criteria and set the rearm delay to whatever value you want. You may want to use 'Cancel All Unmatched Bet In Market' in case your selection changes place (in the case of choosing by favourite order).
In conditions choose 'Number of Unmatched Bets' condition and set to greater than 0.
I've not tested this but it sounds like what you are after.
Or in Excel write the instruction whilst monitoring the unmatched bets count and create some kind of timer to act as your kill delay.
