Is it possible to draw a box in Schematic?

I am using the schematic section to draw my circuit but the item is spread over different boxes. I would like to show this on the diagram.
One way I can see to do it is to drag a sparkfun offset header onto the screen and choose the 1x01 offset option to give me just 1 connection.
I then duplicate it and put one in each corner of the box I want.
I then join then with black wire.
Is there a neater way of making a box?

The simplest option is probably to use the “Schematic Frame” part. Another, more customizeable, option is to create the box you want as an svg image (Using Inkscape or another editor), then load it with the “Schematic Image” part.
