Request for 'Save as PDF' button in forms

Yes I am familiar with this function but unfortunately it isn’t exactly what I am looking for.
What I am looking for would be similar to “Print” but would just save the completed form (prior to submitting it) instead of printing it. I know this is only a slight difference since someone could simply print to a .pdf and get the same result, but it would be easier and possibly less confusing for our customers that don’t use computer very often.
