Single "Not applicable" button at the bottom of a grid question

Question

I have a grid question but it will be possible that  none of the options will apply to some respondents. I could include a "N/A" column and make the respondent check that column for all the rows, but it would be far more convenient for them if I can just put 1 button at the bottom.

I thought I saw a question like this in the Lighthouse question library but I must have been mistaken because I don't see it there now.

Thanks in advance

It is in the Question Library.  Here is a link:
