Back/lay

Hello.

Basically another my trigger adjustment if possible. This one: Bet under

Simple adjustment. After placing a back bet trigger would lay straight away. 
Is it possible to lay with same amount which was matched? Cause from my experience, it happens that - let's say - evens are available, trigger send a back bet but just some money of my stake gets matched. So if I bet with default stake of 100 euro and just 80 euro gets matched I would need trigger laying with 80 euro. If this isn't possible, just laying with same stake which was sent as a back. 

So trigger would back under and then lay immediately at lower odds. For example 10 ticks lower, waiting to get matched.

Example: Trigger sent 100 euro back at 2.0. Got matched. Then immediately send a lay bet at 1.8 etc. 

Thanks
