You're making this a much bigger deal than it is. You have more than 400 posts on this forum and have asked tons of questions (including concerning PPR), but you haven't even taken the first step yet. I suggest you get started already and create your profile.
You have 60 days to complete your profile, so if you don't have a piece of information "by your side", you have plenty of time to go and get it.
So get started and stop worrying about every little detail 3 months in the future. First steps first.
