I often have occasion to draw bounding box rectangles around groups of connectors on panels. It is standard that people want a header of text at the top of that group. The text typically intersects the top line of the rectangle breaking the line of the rectangle for the entire area of the text takes up. I am not seeing any way within the software to edit a rectangle so that I can remove a part of one side of the rectangle to allow the text to sit there and not be intersected by the rectangle itself. Is there some way to break a rectangle into sections so that I can edit parts sort of like editing nodes on a line and create a break in the rectangle to allow this?
