Questions about the HI object and controllers

Hello,

I would like to know if there are some way to connect a controller to the HI object, disconnect and reconnect the controller and still use it without delete and recreate the HI object?
In extension is it possible to keep the physical ID of our controllers connected to the HI?
For example if I have 3 same controllers A, B, and C in order to the HI object if I delete the HI object we don't have necessary the same instantiation with the same order…
And finally do you have planned to have the bidirectionality between max and the controller to use the vibrations, led, etc?

Thanks a lot!
