Sum of Items in a Block

I apologize if this question has already been answered, but I wasn't able to find it in my search.
I have a survey of 63 matrix table questions (in one block, the other blocks are demographic info only) where respondents score each item on a scale from 1 to 4. Is it possible to add the scores of all of these items so that at the end of the survey, respondents are able to see their total score (e.g., if they scored a 1 on all items, can I add a feature where they can see that their total score was 63)?
Thanks so much!
