Hi Dave,
Data import options are limited to only one JQL filter in the eazyBI account.
A recommended approach for locking reports to different filters could be to create different accounts. The full re-import with the changed JQL filter in the import would change all the reports’ contents in that account.
There is an alternative discussed in this presentation that you can implement custom calculated Javascript fields and create in one account several new dimensions with the goal of filtering:
