Help copying blocks from DraftSight to SolidWorks

Hello, 

My company has many assets that they originally made in Autocad (.DWG files). We're shifting slowly but surely to SolidWorks. But, because so many assets are in .DWG files, they purchased a copy of DraftSight for me to help carry assets from the .DWG files to Solidworks drawings.

Generally, this is pretty easy. From DraftSight, I just need to (1) make the asset I'm copying over into a block, (2) make sure it's the color I want it, (3) Ctrl-C from DraftSight, (4)% Ctrl-V into the Solidworks drawing, and (5) I can scale the .DWG asset into the size I want it, and drag it into place.

However, I'm having problems with blocks that have attributes. For example, somebody made the balloons below into a block with an an attribute that is their item number:

When I try copying these assets into SolidWorks, anything that is an attribute doesn't copy over. So, I'm left with a bunch of empty balloons. Does anybody have a good way to address this?
