I use to have different ticked managing system, there was a functionality to relate requests to a single main request, then main request can be forwarded to the support and all related requests can be closed with this request closure.

This is a good feature to have in case there are many users reporting the same issue. 

For example coffee machine is down on floor 4, and all the users located there will report the issue. It's convenient to close all problems at once when machine is fixed, sending same automatic resolution added for the main request to all the requesters.

As I understand in SD+ requests can be linked, but changing the status of main request doesn't affect others and doesn't solve/close them too.

How can this be done?
