change projection angle in Catalina

I used to change the projection angle of the maps with JaVaWa tools.

Because I upgraded to Catalina this is not possible anymore: JaVaWa is 32 bits and is not going to be upgraded in the near future.

Is it possible to change the angle in a different way? 

One option is to download the map in Windows, change the angle and import is back on my mac.

That is a lot of extra work I'd like to avoid

@ Garmin: Can you change the projection angle to the center of the map? At any zoom setting... Google, Apple etc do that standard
