I do not think that what you want is possible using only regular expressions and “Find & Replace”. It is possible and not to complex using a programming language. The following code does what you want:

    #!/usr/bin/env python

    from re import compile
    from sys import stdin, stdout

    regex = compile(
        """(<PortalOBj portalFlags="16" numbOfRows="1" initialRow=")\d+(">)""")
    index = 16

    def create_subtitute_function():
        def substitute(match):
            global index
            replacement = "{}{}{}".format(match.group(1), index, match.group(2))
            index += 1
            return replacement

        return substitute

    text = regex.sub(create_subtitute_function(), stdin.read())
    stdout.write(text)

I attached a bundle which contains a command that uses the above code. To install the bundle just double click it. You can apply the substitution on some text by pressing the key combination “^⌥⌘R”. Since the above is my code I would be careful when you use the command though :).

Kind regards,

P.S.: You can create a screenshot of a single window by using the key combination “⇧⌘4”. After that just hit “Space” and a click on the window you would like to make a screenshot of. This way you do not need to crop the picture.
