Connection between Wix Event and a database collection

Hi,
I have weekly event managed by Wix Event on my website. Only approved members can theorically register to these events and these members are all listed into a database collection (WixmCode). I would like to:

  • create drop-down user input with all members details (mainly first and last names) in the registration form, ie only members listed in the collection database can register to an event;
  • allow each member that wishes to register to an event to clearly see who has already registered before him/her.
    Can these be done now? If no, can I hope it in near future?
    Thanks a lot
    TCCC
