We require at least a 2. type of link ( 3. type if you count "Parent" and "Child" as 2 different linkage types) between tickets which doesn't force you to set one of the tickets as the "Parent" and the others as "Child"s. Sometimes we can receive tickets which only need to be linked together at the same level. For example a customer may inform us a common problem which they have encountered on a bunch of products. In that case all of the tickets have to be considered at the same level.

Could you please consider incorporating different link types for ticket linking.
