[Discuss-gnuradio] Set QT GUI 'extras' from GRC?

[John Murphy]

Is there a way from GRC to set some of the 'extra' parameters in the QT GUI's?
For example, say I want to enable auto-scaling, or set the FFT averaging, or 
set signal colors or names for the legend.
I understand how to do all that after starting the flowgraph, but it takes some 
time and it only persists for the current run. So for some items I would like 
to make a set of behaviors more 'default' on my GUI.
