Change ED 2 to RD

Sorry if this has already been discussed, but is it too late to change my ED2, which I have already submitted, to RD?
Also someone posted that the supplement is due Jan 31, NOT TODAY, and I was wondering if this is true or not

Thanks in advance!

I am also wondering about the supplement. Bump.

Op You should email your regional adcomm to make changes from EDII to RD if that is possible.
