I don't think so, but if in the PropertyManager of the Bolt connector you click the push-pin, when you click OK it will keep all of your parameters and simply allow you to make two new selections and OK again, until you're done.
Hope that helps.
And if you're on 2011 Simulation, you can also afterwards select multiple Bolt connectors and edit them all at once, change a value, OK it and boom, you're done!
