Ability to filter linked issue mapped to a project or list of key which are part of a different filter

• Currently we have multiple projects and we maintain user stories in each of it.
• To maintain test cases we maintain all test cases in a separate project for better tracking and stay organized.
• Test cases / Test tasks are linked to "User Stories" of different projects.

Now for tracking, I am looking at filtering all Test task which are linked to "User Stories" of a particular project. How can I do that? Please share any ideas.
