Advanced Feature - Add Box
You may add a Box to your job. Press the B button or the add button and select Box. The box default screen is shown below. Press the lookup buttons [ ... ] to select to change the fill color and the outline color for the box. The corners of the box can be rounded by checking the checkbox.
Note: A box is always transparent in PDF processing and will not cover a existing stamp. You can cover a existing stamp by using a picture (graphic file). Please see Tips & Workarounds for information.

The next two screens show the edits of the box, variable and constant.
