Ultra Plan Codebase Indexing Limit?

Hi! I’m interested in the Cursor Ultra plan, but I’m working in a large codebase. I know Pro plan limits codebase indexing to 100k files, could I index a 500k+ file codebase with the Ultra plan? This would make upgrading definitely worthwhile and would be useful for power users!

If not normally allowed, would love to work with someone to figure something out that works.
