Abstract submission permissions

Hi,
is there the possibility to allow abstract submissions only for registered users in a given conference?

We know that there is the Authorized submitters voice in the Call for Abstracts settings modal window, but this seems to not allow to choose all the registered users of the conference. Also, in this case the deadline for submission is ignored.

Reading the documentation and some other threads it seems that this is not possible.

Thank you very much,
Cristiano.
