Question About Past Dating/Exchanging Tickets

I bought a pair of tickets for The Color Purple for next week through Broadway Week (purchased at the box office). A work thing has come up, so I'm no longer able to go. I understand that all sales are final, but I'm hoping there's a way to exchange the tickets for another performance. Does anyone have any insight as to whether this is possible? Should I go to the box office and explain the situation? Thanks!

If you can go midweek during the next few week, I'm sure they'll have no issue finding seats for you. September is dead on Broadway. But you have to go day of to the box office.
