Haha I also self-sniped myself by getting caught up writing the barks. It’s such a fun exercise.
The current interpolated values are: mech_name mech_frame pilot_name callsign
I’ll make a note to look into giving more flexibility & visibility into who you can refer to in the barks! I think the reason I defaulted it to only one possible unit was to not have to handle people trying to use like target_callsign in a bark type with no target information (like deploying). But that should be fixed with better viz, now that I think about it.
Glad you’re having fun :)
