This is a feature suggestion. In Jira Plan on Jira Cloud, the filtering options are quite limited. What's worse is that each of the filters are blanket `AND` operations, so you can't do any complicated `NOT IN` operations.
Please add the option to just use JQL to define how to filter the view in Jira Plan.
Examples where JQL would be easier:
- When there are hundreds of options to select it's not feasible to click everything relevant, those lists may be dynamic requiring constant monitoring. For example, finding all issues that do not have a specific label, you can't do that.
- If you want a filter to only apply to one hierarchy level and not to the others you can't do that. Though this is feasible with raw JQL.
