Drum Remap function only for a single Style?

Hi,

In Audya i know we can remap a drum kit for every style without need to save a new UserDrumSet.
On the sd9 manual also talks on remap and save to UserStyle. But on reality the remap function for a UserStyle simply not exist. Only the possibility to EDIT a DrumSet and Save as a UserDrumSet.
No longer have this option?

Thanks

Drum Remap was up to OS2.0 but not a user drum set.
From OS2.0 User Drum Set, there is no Drum Remap anymore?
I hope this will happen again in a new operating system as this is a very important feature.
Best regards

I dont find drum remap... is a big fail
