Configurable Shapes

Great work on the flowchart adrai!

Is it possible to configure 'condition' shape in chart.drawSVG?
For example, use 'condition' but with a rectangle shape and not a diamond shape.

I noticed 'condition' and 'operation' were drawn in their respective js definition files, but due to my specific use case I will need to use 'condition' but in a rectangle shape (using 'operation' with named branches is also possible, but how can we/is it possible to do that).

Is there a way we can go about this?
