De-activating 'Submit' and limiting to one response per user

De-activating 'Submit' and limiting to one response per user

I want a questionnaire to collect only one set of responses per user - and to allow users to amend their responses at any time. This seems to function OK with Respond Many and Save and Resume set ... up until it is Submitted (which clears everything out for a new set of responses).
Can I remove the Submit button - and will that enable me to built  one-response-set-per-user   which I will then report on using a customised report?  If possible, how does one go about it?
Thanks
