Impulse response?

Hello, I have one heretic question, is there a way how to use (own) impulse responses in halion?
Idea was to make IR of analogue filteres.

A lot of IR libraries, especially of gear, are the exact same source but with a different time decay. SO you get an IR library of a vintage Lexicon Reverb and you get a bunch of files like:
-dec-0.5sec
-dec-0.8sec
-dec-1sec
