Stop default pedal assigning in order of adding

There’s a similar request here, perhaps the it can be merged:

Allow footswitch assignment when using "Set parameters as default"

Allow the footswitch assignment to be included in user defaults. That way, any time you select a user default version of a device/block/model, it could already be assigned to your preferred footswitch (or no footswitch at all).
