controlling build effect

is there any easy way to control build effect. right now, it either displays faces in random order or if i use ctrl-f it displays them from left to right. anyway to do top to bottom, etc. also, is there anyway to do a reverse build effect (faces disappear)?

it builds them in the order they were created by default. so maybe create them in a different order.

i guess a “hack” method would be to rotate your model in edit mode and do an Xsort, that should change the order of the vertices starting from one side and going to the other (I forget exactly which axis). That would probably work with some experimentation.
