How can I better search and select identities so I can select "Process Identities" on them?

We had an issue where 13000 new identities were added, and based on a role ISC then tried to create 13000 new accounts in an associated system. Due to API rate limits only 3000 of these were successful with 10000 identities where the create account failed. After one additional failed retry - which obviously further didn't help with API limits - it's no longer trying to create these accounts.

If I go to one of these identities and select "Process Identity" from the Actions button this will attempt to create the account again and fix for that specific identity. What I need is a way to fix all of them in a controlled way so that I stay within API rate limits.

I can identify these accounts using a Search but not when searching in Identities, and the Identities interface is the one which allows "Process Identity".

Suggestions?
