I used to do this, too, until one time when my lab aligned the first frame of my slide film in the mounter, then sent the whole roll through. Since the registration was off due to me having taken the film out of the camera, then reloading it...the slide mounter ended up chopping all my slides on the last part of the roll in half.

No lab should do that! that's unacceptable. Sorry to hear that and hope your lab is better now.
(film loader and accessory now avail at the bay.)
