Antidote: Allow external input to be routed through filter

[Djen]

I recently purchased Antidote for Reason and was glad to see it it allowed external input to be processed by its effects. However, I'd really like to be able to route the audio through the filter as well. Not only would this let me use the very nice sounding filters, but it would also allow modulation and automation on the filter and amp to affect the external audio.
