Move multiple connectors at the same time

Hello,

I currently have a big group of objects linked to another in a model. I would like, in another model, to be able to link this same group to another object. I therefore have copied & pasted all the content of my first model into my second. I am now trying to move the connectors from my first object to my second one.

But it only works one by one! Does anybody know how to move multiple connectors at the same time? I have hundreds of links and would like to spare time.

Thanks in advance,

Arthur.
