We currently have team-managed projects that need to have the ability to have more than 5,000 issues in a project but do not need to see all of these issues at once on the board.

The use case is that we have issues for each customer and then each customer has a sales season linked to it and then that sales season has products linked to it and then those products have tasks required. We only need to see the customer issues and the tasks, not the sales seasons and products. 

There is currently no way of filtering out the issues we don't want to see like you can in a company-managed project which makes the project essentially unusable. I have had to create a personal board for the team to be able to view the issues in their project. It would be great if we could filter out certain issues so we can see the newly created tasks on the board, and not just the first 5,000 issues which contain the sales seasons we don't need.
