InfoPath Dev

I published a form to a custom form library. The Library item has 25 fields, it runs in a browser I've created & saved several items. These items are the "many" side of a One-to-Many relationship w/ the "Schedule" table......so these items are grouped by ScheduleId. When I edit an item directly from the list, the item's field values fill in....I can edit or change, and overwrite the file. What I WANNA do is "open" the next record, write/update, rinse, repeat.....WITHOUT closing Infopath browser form. So far the only way I can figure how to do this is I made a secondary connection to the Main Library, I can iterate thru the items, but of course the fields are reading-only, and I have to programmatically fill the "Main" fields one at a time. I can then write/update the next item. But isnt there a way to fly all the data from teh "next record" into the fields of the main the way they are populated when you select "edit in a browser" from the item?

A colleague of mine recommended I set each of the default values from my Main to the secondary connection's field-twin. I filter to iterate thru my 2ndary, and the form boxes update dutifully. Works great.....except for the choice field.....I'll have to mess with that a bit.
