How to merge 2 questions together to one widget

Hi, I asked the same question in two different phrases (based on answers from the customers I once showed the question with "sorry not to meet you needs, tell us why" and once with "happy to meet your needs, tell us why"... then the customer needs to choose from the same list of topics (multiple choices).
I need to have a widget that takes both questions and show their results as one... meaning sum up the total people that mentioned the topics, regardless the question one or question two, that only differ in phrasings....
Is it possible? can I merge them together somehow in the settings of the dashboard data to begin with? or if I can just do it in widget it is great as well
Thanks!
