you will insert as shown
I would also add in relation/part to avoid any past manual input error
(by experience) this:
merge=" "IF merge==" "merge="-"
I hope this helps you.
I am still a little fuzzy with this due to the fact that I haven't worked with relations but the pictures help me a lot in understanding how this comes together.
From what I am seeing I could have this added to all of my start parts and it would give me the actual part name with every part that gets merged into them.
I will give this a try; it may solve a long standing issue.
if you're merged part is an instance,
then yes replacing it will show the new instance
in part parameters "merge" , source=relation
