jql, which returns stories of related epics, which have a certain label

Question

Can you help we with one jql related question. Precisely I have list of epics which I have labeled as important, so I want only these epics and the related items to be shown in the story map. So, how can do it? 
I can select all epics based on this label, but I didn't find a way to get all their items with sub-query based on these epics. The only solution I found is "Epic Link" in (list_of_epics), where list_of_epics is comma separated list of all epics I want. Obvious this is not the best solution, because I have to update this list every time... 
Will appreciate if you can help me with that.

I think the only available workaround is:

* Add the 'important' label to all issues linked with a so labelled epic.

For doing that, execute your query: "Epic Link" in (list_of_epics)
Click on the button Tools on the top-right corner > all X issues
Select all issues > Next
Edit issues > Next
Click 'Change Labels' > Add to existing > important > Next
Confirm
 
* Now, you have all important epics as well as issues which are linked to them with the 'important' label.

From now on, instead of adding the 'important' label just to the epic, do so to its linked issues all at once in bulk, using a JQL like:

key in (KEY-27) OR "Epic Link" in (KEY-27)

where KEY-27 is the issue key of the important epic.

After executing the query, just bulk edit all the returned issues to add the 'important' label to all of them at once, in a similar way than described on step 1.

* Finally, the JQL to get all important epics and all issues linked to them is:

labels = important

Hope it helps.
