Well, I thought I had a good idea to work around this by setting a string to the formatted text and then use that string in the epilog:

text = Example()
#
parser = argparse.ArgumentParser(prog=sys.argv[0],
description="Example Arg Parse",
epilog=text)

I had to change the Example function to return the string and in a print it works fine, however when used in the argsparse, the formatting is lost...
