I don't think it would matter if you have dates or not, because once you create the PID and enter the name, the next question is about if it's a "non-fictional human" (emphasis mine). Once that's selected as "No" I believe any further PID options are then gone and there wouldn't be anywhere to enter those dates.
This is purely based from memory though - it may have changed or I could be incorrect.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
