How to label Mikrotik packages?

Question

network hardware

Hello.
Myrotica can label packages for various purposes.
It is possible to mark packets of any network device, but is it possible to mark the packets of the Mikrotik itself?
Packet marking on IP 192.168.88.1 does not work.

Outgoing packets are marked on the output chain.
Describe the task in more detail, for specifics.

Answer 2

Packets are tagged only for devices on the network or networks that this microte is routing. Marking in the mangle works at a level higher than the microt's own traffic.
