AutoCAD Civil 3D :: Dynamic Blocks From Several Different Files Referenced In One Tool Palette

I've begun to create tool palettes to organize my blocks and often-used items. I have no trouble creating the tool palette, inserting regular blocks, export/import of the tool palette and groups, however my problem involves Dynamic Blocks and the fact that I keep each seperate dynamic block in a different file. I do this so that I can easily insert the block into a new drawing.

I'm able to drag the dwg file onto the palette (from explorer to autocad) just fine, that way the block's reference in the palette is the original file. Although when I take this method, I don't gain the lighting bolt to signify a dynamic block.

To get the lighting bolt I insert the block into an empty drawing, save it, then drag the block over to the palette. The problem with this is that the tool palette references the saved blank drawing, not the original block's file.

My endgame is to have a tool palette that contains my dynamic blocks and that will be eventually exported/imported to other computers everytime there is a major change. I also want to be able to change the original block's file and have that change be reflected in the tool palette.
