Yes you can do this with lines and some other objects.
Click "Elements" from the left menu. Pick "Line", then on the top menu click "Stroke" from the top menu.
Select the "Dashed" choice, change "Line" and "Gap" to say 10 for example and press okay. You will see the dashed line. Change any of these options to your liking. There are many choices you can make.
You can do the same thing with other elements as well, rectangle, circle, square, whatever shapes there are.
Like we said you can do this with many objects. Text being another one. Make some text. You can click on "Text Color" on the top menu and pick the transparent one. Then click on "Stroke" then pick for example, Put "Stroke at 3", change color to red, Pick "Dashed", "Line" to 3, and "Gap" to 6. Then press okay.
