Bc2000 (for the BCF2000 & BCR2000)

Hi everybody and seasonal greetings to you all:)

I have a little problem that I don't know how to solve which is this:

I have a sequencer called KLEE, (soft version) and I want to assign CC function to BCR pot, that is 0-127,  but in the Klee sequencer it has 4 steps only, which are: A=1...B=2....C=3...D=4, making it hard to turn,  between them, they are too close.
After number 5, nothing changes,5-127 is 'dead'...

The problem is the resolution of Klee is 'too close' together, I would like it to make it like A=0-30...B=30-60,...C=60-90,...D=90-127, or similar...even by 10 is OK...
I have no problem to assign it to a button, but I ran out.
Is it possible and how?
Thank you in advance,
best Karel
