can you associate a Change with another Change?

Hi ​@Louby99 , there is no direct way to link/associate one change request to another. However, it can be made possible if you add a custom field for change requests. Navigate to Admin > Field manager> Change fields> Add a custom field “Related Change request” (you can configure it as shown below):

Then while creating a new change request, you can enter the existing change request ID and link it.
