ACAD BLOCK AS CUSTOM BALLOON

Fairly new to SW, completely lost on how to accomplish this, or if it's even possible. I need to make a custom balloon to match the one in the attached AC file, including attaching attributes to the leader as shown. I can import the dwg into SW with all of the attributes intact, but I don't know where to go from there. Our expert SW user is as lost as I am. Thanks for any help -
