[Solved] ASA external roller shutter motors and GO-16 16-channel remote control

Hello,
I am struggling with the programming of 21 roller shutters installed some time ago by a company that disappeared and did not complete the installation. External roller shutters with ASA brand tubular motors with obstacle detection, there are two ASA GO-16 16 channel remote controls. The roller shutters have been powered several units per power supply ( no access to the boxes )
Questions:
1.Is it possible to program each roller shutter on a separate channel without disconnecting the power supply on the other multiple roller shutters, if so how do I do this?
2.Is it possible to program each roller shutter on a separate channel and at the same time the selected roller shutters together?
3.How do you delete the stored end position in a roller shutter which stops in the middle of the window?

So far I have managed to program the roller shutters several per channel , according to the given power supply, but the customer wants to control each roller shutter independently and there is no way to get to the junction boxes due to the finishing of the house.
I would like some help in figuring this out.

Ad.1.I solved a similar problem by going into the box and placing monostable switches (fridge switches - I had a dozen or so) in series with the drive, sticking their heads out from underneath the boxes and pressing them while programming, disconnecting the power supply.It's worked well for me for years.

This is an idea. I've come up with the idea of cutting the cable, except that I'm treating it as a last resort ( no cable supply, cramped in the box, 21 blinds to cut is a lot of time ) I need to find a quicker way.

After three days of work, fixing assembly errors and working out how to erase and program these drives, I have managed to combat this topic. The topic is now closed.

Solution:
1.fix mechanical problems with roller shutter operation
2.delete existing roller shutter configurations
3.re-programming the drives on individual channels and creating groups of common channels.
