Visio 2010: Moving Multiple Connectors, Sequential Diagram [closed]

Question

I am trying to move multiple connectors that connect lifelines of objects, but the connectors become unglued if I select more than one and move them. Is there a way to move all of the selected steps down one or two connections without having to manually reattach one at a time? This would be very handy in inserting new messages that would go above existing ones.

To clarify, are you aiming to maintain these connectors on the same objects, just lower down on each object? – Circumferential

Precisely. So far I've been able to get along by not gluing at all, but this then results in problems if I want to move objects around, or change their spacing. – Szymanski
