@Diana__Jane if same eoi for 189 and 190, then for example nauna ka ma-invite for 190, parang di na ata ma-invite for 189, kasi di na ata nila ma-access nun ang eoi, and vice versa. So they usually submit different eoi's. But if no issue naman sayo kung sino mauna, then having only 1 eoi should not be a problem.
Good luck sis! Sana dumating na positive assessment mo.
