Can I submit I485 for EB1a without receipt for NIW I485

I submitted I485 for NIW (I140 pending) on July 2, no recipt yet. But I got my EB1a 140 approved now. Can I submit another I485 for the Eb1a without recipt for the NIW 485?

WIll I get two A number?

How about if I withdraw the NIW 140? is the I485 will automatically withdrawn with I140?

really do not know how to do now. also do not know how long I need to wait to get the recipt for NIW 485.

Thanks!
