Automation Help Required Please

[Lagos]

Hello everyone, Bet Angel user here for well over 20 years looking for a bit of help please.
I would like to be able write an Automation file to do the following.
Back Guardian nominated selection 1 at BSP, then in running when the win profit is a known number lay back an amount at probably 4 price points down the ladder at percentage of that number.
IE if my BSP on my initial back bet is 14 I want to be laying back at a bigger price than if my BSP is 2.5 .....if I'm backing at 2.5 my lay backs are probably 1.3 and lower or I'm giving all my profit away. At larger BSPs I have more to play with.
The complicated bit is its possible there could be 3 bets on different runners in a race ....(guardian nominated selections 2 and or possibly 3)and they all need the in running lay backs.

Thanks .
