title: JIRA Query (JQL) to filter those issues within a certain set of EPICs
body: <p>I am currently editing the Quick Filters of my Agile project in JIRA. And I need one where I see all the issues from a given set of epics. I am using something like</p>
  
  <pre><code>"Epic Link" in (ABC-1, ABC-18)
  </code></pre>
  
  <p>where ABC-1, ABC-18 are my epics. The problem with this is that I need to update the query everytime I add a new epic. Instead, I am thinking if there is a way of getting the list of epics that I care about via another search and merging the two into another query.</p>
  
  <p>So for instance I have all the EPICs that I am interested (1, 18) with components set to "XYZ". 
  So I want to do something like</p>
  
  <pre><code>"Epic Link" in ([Get list of EPICs with component XYZ])
  </code></pre>
  
  <p>How do i do this?</p>
