I am not exactly sure what you mean, but the new connector feature of fracturing is not a tag. It connects objects that you throw under the generator. If you don't want to fracture them and only want to connect them you can turn off all sources.
The dynamic Connections are the standard dynamic connectors that where already in Cinema4d. You can use any kind, be it spring, Motor and all default connector types.
On Grey Scale Gorilla you can find a very good introduction Video on the new fracturing by Chris Schmid.
The objects Insertion modifiers are an extension of the current modifiers (like alt for parenting) to multiple objects selections.
