Adding columns with information on parallel or downstream item

Dear Community,

is it possible to add a custom column which contains information about a task on the same level or downstream?

I have a Playlist with approved lighting versions. Now I want to add a column showing the status of the latest comp version of the same shot.


I want conditional formatting in a Shotlist based on Pipelinestep Lighting > Assigned to > contains a specific Person. (Conditional formatting not possible in Pipelinestep columns afaik, so I’d need a custom column I guess.)

Thank you in advance for your advice!

Best regards,
