How to create a linked issue filter?

[dar]

Problem
We would like to create a filter for a dashboard overview.

We want the filter to search in a specific project AND search custom issues ('Requirement') for a particular custom field to return all linked issues (Solved By). 

In this way, we could see all epics, stories and tasks across many team projects that are linked to a Requirement issue.

Steps to Solve the Problem

We confirmed that ScriptRunner (currently using a free trial) can do this but my company does not have many more use cases for this expensive plugin. 

We looked into JQL Search Extensions but it seems the linkedissue function is limited in the issue types it can search (see below). 

Are there any other plugin options for creating this filter? Thank you.

I think this plugin might help you.

Enhanced Search (JQL and Subqueries)

It is about half the price of Scriptrunner.

Specifically I think you could accomplish your desire with the linkedIssuesOf function.
