Synergy Monitor Setup

Question

I have a unique setup for my monitors

[PC1 Monitor1][PC1 Monitor 2][PC1 Monitor 3]
                        [PC2 Monitor1 ]

I want the left of PC2 to go to PC 1 Monitor 1 I want the right of PC2 to go to PC 1 Monitor 3

This problem can be solved if I can specify the starting X,Y of the target monitor

something like:

0%-100% of PC2 goes to (100,200) of PC 1

0%-50% (Vertical), (300->310px horizontal) of PC1 goes to PC2
