Thanks. I'll give it a try. Adding a date to the file name is genius. I feel rather silly for not thinking of that.
I hope I didn't shoot myself in the foot. I keep one generic resume that I then taylor to each specific company as needed. I realized too late that the first resume I uploaded included level d sim time in my part 121 time. Not sure if it matters to them but I normally don't include sim time when applying to airlines (part 135 and part 91 jobs sometimes want the sim time included b/c it can be and it helps lower insurance). So the correct resume actually has a little LESS flight time than the first one I uploaded. Hopefully I can just upload several and bump it out like you said.
