Saving modules ?

[Braserox]

I have modified polysynth modules and renamed the module inside a mux container.
I can save the container , but how do i save the new polysynth as module to be avaible for other projects ?
I have not found the save option.

Unelegant solution i found is keeping all new synths modules in a mux container and dragg them into new mux container when needed.

Indeed currently the Polysynth cannot be saved as a preset.
