This is possible with $var(...)s.  Not sure about AVPs.  I use it, it 
works for me.

Now, what doesn't work is using nested transformations or arithmetical 
operations on numerical transformation values.  They won't be evaluated 
properly.  Have to assign them to an outside variable first.  For 
instance, can't do something like:

    $(fU{s.substr,fU{s.len} - 10,10})
