There are such factory presets for some SDXs. That hasn't changed
in SD3. What has changed is that you can no longer save a selection
of drums as a preset yourself. You have to save a complete preset
and then you can choose to only load the toms from it.

Possibly. We have had other users ask for that. However, our intention
is that most changes to the MIDI mapping should be done in the
"MIDI in/E-drums" tab, in the settings. There you can save and recall
the total mapping.

You can save a full preset and then choose to only load the mixer part.
