If I understand what you’re asking, (I’m a little muzzy at the present,) yes! that should be fine.
If you’re wanting to add a “node” to an existing pattern piece, you will use the “Insert node tool” a couple buttons below the tracing “Workpiece tool”, make sure you tell it to add to the proper piece, & then go to the detailing screen, shift it to the proper location in the list of nodes for the pattern, & remove the exclusion status of the node.
Or you could just re-trace the whole thing. That is easier until you get used to seeing the node list.
I hope this answers your question!
