Lay inplay certain ticks below BSP with green & stop

[delboy1234]

Have been trying to set up automation for a strategy that places 3 in play lays on a horse in running and then greens up for a profit on each with a stop loss in place.
With the help of some knowledgeable members on the forum I got all of the calculations set up in Guardian. It imports reduction factors from the file and Guardian does the calcs.
So current rules:
Import stored selections from file
Store BSP
BSP * reduction factor
3 lays placed at correct entry points

All works fine but the problem I am having is greening up and setting a stop loss.
I want to green up each lay for a set amount of ticks profit and apply a stop loss of 25%. Is there a way for Guardian to store the lay bet price when placed? So then I could do a calculation of price +12 ticks and apply that SV to green. Same for a stop loss.
Or if not, is there a way of storing when a lay is fully matched and then linking this to a separate back bet for greening?
I tried all the different settings I can think of but I just cannot get this to work. Thanks in advance
