Ability to disable complete application link activity

We have the following use case:

We are Using Jira and have 2 Confluence instances (A and B) linked with application links. Now in the Jira activity stream the activity of both Confluence instances are shown. As an Administrator I want to disable the activity stream for a specific linked application (confluence instance B) for all users. Because in this Confluence instance B nobody has a user and when a user creates a dashboard with activity stream gadget in JIRA, the activity of Confluence B is always active.

With this active activity the performance of Jira is worse. Everytime a user opens a dashboard with activity stream active Confluence B activity in Filters, the activity stream gadgets need up to 15 seconds to load. When the user disable the Confluence B activity in Filters, the gadget loads in 3 seconds.
