Liability only against the lay side.

[Shamrock]

Hi,
Just a small problem with the one click screen and the liability setting.
I pick out my football games early in the week and depending on my findings I assign them to a specific status, e.g. Lay Home Team, Lay Away Team, Over, Under, etc. Each status has its own bank roll. So if the liability for one group is 250, it’s easy to set the liability to 250 and go through this group then reset the liability and do the next group.
When I go to the one click screen and set the Liability to 250 and the price is 3.05 / 3.15 the stake sets itself to 116.28, aligned to the 3.15. If I reverse the screen and go to lay at 3.05 the stake is still 116.28. Is there any way to link the liability to the back price, either on the one click screen or another screen?
At the moment I am loading them in through excel but I always seem to have problems with excel and some of them not loading.
Any help appreciated.
