Count of Linked Issues from another specific single project

[Pree J]

We have a team project SRS which is used to handle Service Requests.

We also have project SOS which is used to handle escalations that are raised against Service Requests under SRS.

While an escalation is raised, we request to input the Service Request Key of Project SRS so it can link based on our automation rules.

Now there are several other projects that get linked to SRS - call it Project ZZZ

In order to arrive at a metric to capture volume of Project SRS tickets that has multiple escalations (Linked Project SOS) - I created a query, but the countofissues also takes into considerations linked ZZZ Issues taking the count to more than 2 and defeats the purpose

How can I leverage the query editor to:

Provide me with a list of Project SRS Tickets that has more than 1 linked SOS issues, without having to consider if there are any ZZZ Links or not?
