Back out of your lay in stages

[aceporty]

Hi guys,
I usually trade two footy markets in sync, one with a BTL and the other LTB, my question regards the LTB, what i want to do is reduce my red in stages at certain price points to reduce red. An example is lay at 12, then reduce loss in stages at by rebacking at 10, 8, 6 and 4 using the stake of my choice, of course I can do this manually by waiting for price to come down, but is there a way to input stakes at begining so I don't have to watch the screen for long periods.
Thanks in advance.
