Alignment of field captions with tabsheet in form

I am using a Tab sheet inside a form to handle mailing and physical addresses, however the captions do not show next to the fields. I would like to have the captions in the circled red area, not on the tab sheet, but next to it, see image. Is this possible

Perhaps you should take the inner tabsheet outside the form and make separate forms with fields in each of its tabs.
