I read about this novel method last year. I tried it once and it was pretty successful.
You press the dough into the tartlet shells and then freeze the shells for about 10-15 minutes. Then, (this is the different step) - you invert the tart molds onto your baking sheet, and bake as usual.
Good luck.
