Ticket links / Collective Tickets

It should be possible to link tickets so that you can jump directly from one ticket to a related ticket.

This would help with the processing of larger service cases.
Example:
Ticket 1: Overview Ticket: Storm Damage (to keep track of the entire process and and higher-level tasks like insurance processing etc.)
Ticket 2: system failure (employee A)
Ticket 3: damaged PV modules (employee B)
Ticket 4: damaged fence (service provider C)
All tickets belong together, but are handled by different employees and the processing times vary. So individual tickets would simplify to keep track of the processes.

Tickets for different facilities should also be linkable to each other. (e.g. there is a damage to a shared power line -> individual tickets for each facility, but both get linked)
This would also allow service technicians to be provided with tickets that have similar error patterns.

This is what it could look like:
