Currently, that’s a yes. There is a comment of @Jochen_Trappe announcing this feature for a future release
but we don’t know when it will arrive.
I don’t think it would be a problem in that case. My script doesn’t officially support the X-Touch One though (it is said to mostly work, but I don’t own the unit and cannot test with it). Nevertheless, there are several other user scripts available for the X-Touch One as well.
