Generating Report from Custom HTML survey Responses

Content

Hello dears,

We are using a custom html survey (made entirely out of an html template without the use of any "Question"). It is a matrix table which contains 5 questions with radio button answers for each. When completing the survey we've noticed the survey responses aren't recorded in any of the standard Service Cloud reports made available to us (they don't even record that the survey has been "started" or "completed" once the responses are submitted). We would like to be able to benefit from the reporting feature for this survey.

Is there any way to create a custom report that can record the responses of such a survey? Any assistance with this will be greatly appreciated.
