Have been searching the different options but cannot find any betting assistant (or whatever they're called) that will enable me to program the following:

Click on the far left BACK price to submit a bet for £30 @ 2.0
Click on the middle BACK price to submit a bet for £20 @ 5.0
Click on the blue BACK price to submit a bet for £10 @ 8.0

i.e. all I want to do is click the mouse button and the bet & stake submitted are fully customizable according to which back (or lay) button I click out of the three on screen.

I can find ones that will enter a bet immediately on the click of the mouse but it is always at (or around) the price clicked.

For years I have used some software that will enter what I want (e.g. I will click to back a horse and press Esc which will enter £30 @ 2.0 and submit the bet) but it is struggling with the new interface.

Hope this makes sense, can anybody help?
