Quick way to add users to permissions on their respective PAM accounts?

Hello. We have decided to allow our users to "view passwords" on their PAM accounts (of a certain tier). I am going through each of the PAM accounts and adding individual users to the "view password" permission on their respective accounts. Is there a quick way to do this? It's a bit of a long shot I know, as the user for every account is different, but I thought I'd ask as we have hundreds of accounts to modify.

Thanks!
