Is it possible to modify an SMT pad to look like the one attached? If so,
how is that done?
Someone please answer...

Your picture just shows a plain rectangular pad. You can make such pads
easily. In the package editor of the library place an SMD of any size
and then use the CHANGE SMD command to alter the size. When you type
that command you get a drop-down menu with the preset sizes listed, and
at the bottom, a line with three dots. Choose this and you are given a
window where you can insert the dimensions you require. Maximum value of
either x or y is 0.516024"

Thanks John,
Take a look at the pad again, it has (8) sides not (4).

Sorry.
It looked more like a rectangle with a shaded edge in my picture viewer.

If you are talking the black C shape that is not possible without DRC
errors in 4.1x. You could use 3 rectangular pads but DRC will flag it
with pad to pad distance error.
Named copper is not allowed in the lib parts. You can adjust the solder
stop mask to any shape and use a larger rectangular pad with no stop
active. Or make the correct shape stop mask and add a named polygon to
the board after placing the part.
Named Polygons in lib's is a frequently requested suggestion.
