Split Kontact Patches?

[skank]

okay have totally reworded this hope its clearer, I should have put it first time like this,

For eg, I have Kontact Patch A, (maximum key mappings from C-2 to C8)
and I simply want to split it into 2. So there will now be 2 new patches B & C.
Patches B & C must be keymapped from C! - C5. I hope thats clearer.

Can anything do this en masse, its taking for ages manually?

thnx in advance
