How do I create dependency between ranks of 2 entities?

[Ravit Sadeh]

I have the following project structure in my organization:

1. Escalation Project - Managed by the field team and reflect customers's issues

2. Engineering Bugs - Managed by the R&D team, and includes reproduction of the escalation, technical debt etc.

The relation between an escalation and a bug is a link called"Escalation bug". A bug can be associated to many escalations in case several customers experienced a similar issues. A bug can also be related to other bugs via other types of links.

The Business Requirements

I would like that the field team will prioritize escalations using a scrum board, and that the R&D team will be able to see the escalation bugs prioritized accordingly, hopefully in their own Scrum board.

Script Runner

 I am exploring ways to do it using Script Runner - up till now was able to get a filter with prioritized escalations and their escalation bugs.  (I am a beginner) 

Is there any way to extract the associated bugs from this filter to a bug's filter while keeping the escalations' priority?

Can anyone help with a solution that will satisfy the business requirement?

Many Thanks and sorry for the long post....
