Ductwork Fitting Connection Take Off

[rustific41657]

Im producing a schedule for ductwork pieces & fittings. I would like to include any take-offs in the schedule. for example a 800x800 x 1400 long duct piece may have either square duct or round duct spigots connected to it.
can this be flagged that piece number xx (square duct) has spigots connected

cheers

Please see attached image for reference.
Take piece number 400. It has piece number 401, 403, & 405 that is to be manufactured with these pieces connected in the factory. i have schedule that i have created with all of the manufacturing details that are required.
is there a way that i can highlight on the schedule that automatically displays that piece numbers 401, 403, & 405 are connected to the base piece 400

cheers in advance
