How to place unmatched bets at SP prices

[sikan]

I use TSM along with BA to place bets on horse racing markets, and to do that I log multi excel sheets through BA linked to the TSM (the stacking machine) software, all is find until I run in to situations when the software trys to place a bet on a horse that its odds keep on geting shorter and as result it does not geting matched before market goes live.
Is there a way that I can make BA to keep the unmatched bet until market goes live and to match it at SP prices.

Thank you

You need to put this question to TSM support. They are in control of what trigger is sent to BA and the trigger needs to contain the appropriate modifier to request a keep SP bet.
