Is there a way to have my threads from several accounts from several email addresses to be attached to my account?

I have worked as a consultant and an employee for a number of companies and have made many posts using several different email accounts over the years.  I find it useful to check out the answers to past posts when working with the same parts for a new company.  However it is hard for me to remember all the posts so I can look them up.

Is there a way to have my past posts be somehow attached to this account so I can easily just use the my posts tool to review previous posts and answers to them, if I supply the old email addresses for my previous accounts on E2E?
