This question relates to a series submission, where the parent and child files have already been reviewed by PAAB once and multiple comments have been received.
In order to be efficient, we would like to continue the review with one file in the parent-child group. Are we able to move 1 of the files through the review process to ensure PAAB alignment or do we need to submit all 4 files at once? Can we submit just one of the child files or does it need to be the parent?
