There may be a work around in the short term. If you split your SFM into sections then on the left you can select the section. Or you could just add one section which could be blank or have a couple of fields on it for save. I think its logical that when you are viewing the SFM as a section rather than the full view of all sections it would have the save button. So in your scenario you could encourage populating the SFM section by section or you could ask them to access the save section once they were done. no scrolling just switch view then save. I would be interested to know if this works for you.
