Double dig on Sanwa Mt-4s

[setecastronomy]

I have a double dig transmission (front dig, 4wd, rear dig) which can be managed with a single servo and 3 positions. I would like to activate front dig with button sw2 (push mode) and rear dig with button sw1 (push mode). Cannot find any way to achieve this. The dig servo is on aux 1 channel.
If aux 1 type is set to STEP AUX I can easily switch between front dig and 4ws pushing sw2, but I cannot set the 3rd point. With POINT AUX I can define the 3 servo positions but I can only cycle between them pushing the same button more times.
Currently I'm managing the dig servo using trm4, but it is difficult to operate and cannot be as fast a pushing sw2.

Any idea ?

Thanks

I did some experiment with a spare servo. The best I could achieve is the following: aux2 type set to point auxiliary with 2 points, 100L and 100H, controlled by trm4. Sw2 push activates aux2.
Using trim on aux2 I should obtain the 4wd position, setting epa I should set front dig and rear dig.
So when I need dig I push sw2 which is fast and with trm4 I can choose between front or rear dig.
I hope to try this setup in the week-end, I cannot find anything better.

Hi
Do you have a picture of your transmission. I'm interested in!
Thanks
