Presets are stored in the UserPresets folder in Factory and User folders (banks).

Is there a native way to show bank headers in the preset browser's flat list?

So instead of this:

Factory 01
Factory 02
Factory 03
User 01
User 02 
User 03

it shows something like this:

- Factory Presets -
Factory 01
Factory 02
Factory 03
- User Presets -
User 01
User 02 
User 03
