Phab: conditional approval

Hi devs, When reviewing a diff on Phab, I can "accept" or "request changes". Sometimes, though, I want to do both: I suggest very minor (e.g., typo) changes, but then when these changes are made, I accept. I'm leery of making the suggestions and saying "accept", because then someone working quickly may merge without noticing the typos. Does Phab have such an option? Thanks, Richard
