So yes, you can, by changing the drawing area in the options block(the  
one called “top\_block” in the top left). But looking at yourflowgraph,  
you can probably accomplish what you’re trying to do withonly two  
signal sources. Just use a variable to set the frequency ofyour signal  
source instead of selecting between multiple signalsources.
