Visibility settings on individual attributes in a block

Hello,

I'm using about 10 attributes in my blocks at the moment. For different instances within the same drawing, some of the attributes need to be turned on or off depending upon the need and the particular piece of electronics the block is representing. I know you can set the visibility on each attribute when the block is initially created, but can you turn on/off individual attributes after the block has been inserted.

Thanks in advance, Jeff
