Amazfit Watch faces

Hello everyone, I'm trying to make a dual time Watchface for my gtr2e with the watchface maker 2 (V7).
I've read somewhere that it's possible to do the first time on digital and the second time with the anolog one. However I could not figure out how to make an offset for the analog time. I see that in the JSON there is a parameter for the start and end angle (so this could be the thing to change?) but it can't be changed in the tool. Am I missing something? Any help would be greatly appreciated.
Thank you!

It is necessary to draw an image of the hour hand rotated to the required angle. Then the analog time will lag behind or ahead of the current time by several hours.

Thank you very much for the response and great it comes from you directly! Very appreciated.
