maintaining a neat cable bundle

["Christopher Glaeser" <nospam@xxxxxxxxxx>]

I need to run several cables underneath the eves of a house, but would like
the option to easily add more cables to the bundle in the future.  The
screw-in Panduit style cable tie wraps would be ideal, except that adding
another cable would require unscrewing all of them and replacing them.  I
don't mind the cost of replacing tie wraps, but don't want to unscrew and
rescrew the tie wraps to add a cable.  Is there a screw head that is
specifically designed to hold a tie wrap, or a Panduit style tie wrap that
can be untied and retied?

Best,
Christopher
