Hi and welcome to Arturia forums.
I'm not sure what you are looking for. It's possible to have controls including pedals to use all MIDI CCs. A Sustenuto pedal is a on/ off kind of thing. But an application need to support Sustenuto, to make it work like it. It's not enough the keyboard can do it.
Arturias Piano V2 does have a Sustenuto pedal function.
I think all Arturias have at least one Hold function of some kind. They work, if they are set to work.
Most applications have a Hold function. But i think it's mainly Piano applications that have a Sustenuto function and not all of them have. That depend on the application.
I think your question is more about what each application can do, than about the controller.
