Is it possible to change my blurb?

So, my story is in the submission queue right now (number 27 or so last I checked). I gave it a kind of meh summary--I'm bad at writing blurbs. Will I be able to change it later? I know I can now, but it will kick me back to the bottom of the queue and it doesn't strike me as that urgent.

Thank you!

Yes, I have done so.

I'm glad it can be changed, but since your story might change as you write it, it makes sense that you can change it.
