Ability to search in JQL for Linked Issues of a specific Issue type

Problem

The current JQL function LinkedIssue() doesn't look for linked issues of a specific issue type.

Suggested Solution

It would be nice to have the option to improve this function making it able to search for a specific linked issue of an issue type, for example:

project = Test and issuetype = Task and linkedIssue(Epic)

Why This Is Important

This will help customers who perform these specific searches to use it inside automation rules and other reports, and gadgets.

Workaround

The current workaround is to use a third-party app.
