Make linked parameters invalid in suppression state?

Hello all,

     I've skimmed through the forums and my SW textbook and have come up with nothing.  My question is:  Is there a way to make certain parameters in a design table as"N/A" when the values correspond to a suppressed feature.  Everytime I manually put in "N/A" and go back to my model it say it requires a value.  I know I can just ype any old thing and it wouldn't matter since the feature is suppressed but I wanted it to look cleaner so when my list grows, it is easier to skim through.

Thanks in advance! I feel like I'm getting in over my head with these configurations as I've only got 2 weeks of on the job SW training so far.  School didn't help much in learning the potential of the program.  Basically extrude this, and cut that, and you get a part lol.
