Common App / Slide Room linkage for UVA?

Timeline question. Suppose you have UVA slide room with all materials ready to go, but you can’t submit before you submit the Common App (the system just doesn’t allow you to). Deadline wise, when do these things get linked? Daughter is planning to submit Common App tomorrow, and I am worried about Slide Room since it’s due on the 1st of November as well. How do these datelines line up?!!! TIA

Submitted my app three days ago. Two days ago, I submitted my piano portfolio. I think the app is attached to slideroom rather quickly, but I can’t give you a definitive answer.
