Editing Pro Account user name and tying old role to new Pro account

I just joined IMDb Pro and made a new account but because it wanted to tie to Amazon, I now have no idea how to claim an old role and that regular account. My new Pro account is Tim Raines (II) but the "role" I had is Timothy Raines, as an art department for Cuckold Picasso. How to I merge everything and ideally, since "Tim Raines" is taken, I'd like to have "Timothy Raines" rather than "Tim Raines (II)".
