Possible access to UE4's bloom blurs?

How can I access the smaller blurred textures generated for the default bloom to create new post process effects without re-computing them myself?

Bloom can be implemented with a single Gaussian blur. For better quality, we combine multiple Gaussian blurs with different radius. For better performance, we do the very wide blurs in much lower resolution. In UE3, we had 3 Gaussian blurs in the resolution 1/4, 1/8, and 1/16. We now have multiple blurs name Blur1 to 5 in the resolution 1/2 (Blur1) to 1/32 (Blur5).

Thanks!

Looks like this needs a bump - lacking any way to do a custom bloom with reasonable performance has gotten in the way several times over the past few months.
