Hello,
Problem description:
My team uses a project , Project A.
In Project A, some issues have epic links to other issues. Lets call one of the issues in Project A Issue A1.
Issue A1 has an epic link to Issue B1. Issue B1 is in Project B.
Issue B1 has an epic link to Issue C1. Issue C1 is in Project C.
Issue C1 has a value in the fix version field. This value is important to my team as it determines when we will work on Issue A1. What our team wants is to, when we do our planning, easily see which issues in Project A are to be prioritized.
A picture is attached below for clarity.

So far, I have tried to create a filter. I can successfully obtain all issues in Project A that fit my criteria using the query:
issueFunction in hasLinkType("Epic-Story Link") and project = "A" and summary ~ "B*"
This gives me a list such as:
Issue A1 in Project A (Fix version of Issue C1: w1)
Issue A2 in Project A (Fix version of Issue C2: w3)
Issue A3 in Project A (Fix version of Issue C3: w2)
My questions are:
Thank you in advance for your help and let me know if anything is unclear.
