adding blank attribute fields to blocks

[Anonymous]

I am using ACAD Civil3d 2014. I have the map utility loaded

I created a drawing for a client and created blocks to represent handholes. They now need to go back to the blocks and add the HH number and fiber size. How can I add to blank att fields to the blocks so that I can send them the drawing and have them enter the information manually?

thanks in advance. 

I searched around and only see solutions for adding attribute labels to the block.

that was easier than I thought. Map->Attach Object Data

thats a little different than a Block attribute
