[Discuss-gnuradio] Passing messages to block values?

GR 3.7.4 now has a message output on the QT GUI Frequency Sink. Is there way
in GRC to pass this message to a value field within a block? For instance,
pass it to the Center Frequency value in the UHD Source block to retune the
hardware?

Is there a way to disable the frequency re-centering when the mouse is
clicked, that way I could pass the frequency to a channelizer without
altering the main spectral display.

Thanks,
Lou
