Upper Limit to Number of Unique Agenda Roles

Hello!  Is there an upper limit to the number of unique agenda roles that can be created and used over time? 

For example, say I wanted to create a spot on the agenda called "Meeting Theme - X", where "X" is a different theme for every meeting without repeats.  Can I do this freely, or will I be limited to, say, 500 possible uniquely-named agenda roles?

Thanks in advance!

There is no upper limit, you might find your roll reports become useless though.

Thankfully this "role" has been eliminated from historical reports.  Otherwise, you're right - the role reports would be a mess!

Thanks again!
