Another issue with 3D/collapse transformations

Question

Hi!
Here's the situation:
I have a kinetic text animation in which the ae camera is rotating and moving in the 3D world. Some of my text layers have the roughen edges filter on them. When I turn on motion blur for those layers, it looks funny -propably because the roughen edges filter is affecting the motion blur (wrong render order?). So I tried my number one solution to these kinds of situations: precomposing. But when I precompose the text layers, I need to also turn collapse transformations on in order to maintain their position and rotation properties in the main comps 3d world. Which kind of cancels the purpose of the precomp because the render order changes back so that the motion blur gets applied before the roughen edges (and it looks funny again).
So how do I make sure that AE renders roughen edges first and applies the motion blur after that? I constantly struggle with render order issues like this and I have never come up with a simple solution that doesn't require several precomp generations.
Any help will be appreciated!

Thank you for your reply!
I was afraid that the answer would be what you stated. It sure would be great to have some way of manually changing the render order for effects in AE, maybe I should make a feature request about it. I have heard many pros asking for nodes in AE, and if I understand correctly, that could be one solution for these kind of issues right?
In the meanwhile, does anyone have a script that would automatically create the required precomp hierarchy for a 3D layer so that these kind of effects could be achieved more easily?
