recording automation from one controller to multiple CCs

Is there a way to do this? I have a breath controller and would like to record the automation to both modulation and expression.

I think you can do that with a couple of Transformer MIDI Inserts.

I haven’t tried it but it should be something like this:

Okay - tried that configuration, and no luck so far - only CC2 is recorded. I haven’t used Transformer before, but I wondered if that could be used. The documentation is pretty scant. Will try some variations on this later tonight. Thanks for your help!
