Transfer all channels of mc.function to another mc.function

Hi, I am wanting to transfer all channels from one mc.function to another, but I am struggling to get it working...

With a standard function object I can wire the dump outlet into the inlet of the second function object and everything copies across, but due to the documentation for mc specific messages being incomplete (things like setvalue have no contents in the mc.function reference pages), I'm not sure how I can do this with mc.function.

Heres what I have gotten so far:

Any help would be great!
Many thanks,

james.
