you could still do that by:
* creating a gnlsource with the segment you need without the looping mode
* putting that source in a composition at the position you need
* using that composition in the top-level composition with the looping mode on
and the required media_duration

Ex : you want to use .5s of a clip 2min in it and repeat it for an hour every
second:
* gnlurisource1
** media-start : 120s      # 2mins it
** media-duration : 0.5s   # take 0.5s
** start : 0               # which will go at the beginning of gnlcomposition1
** duration : 0.5s         # for 0.5s
** looping : FALSE         # without looping
put gnlurisource1 in a composition (gnlcomposition1)
* gnlcomposition1
** media-start : 0         # standard
** media-duration : 1s     # Take 1s of the composition
** start : 0               # which will go from the beginning of the parent
                           # composition
** duration : 7200s        # for 2hours
** looping : TRUE          # and loop every second (media_duration)

And then put gnlcomposition1 in your top-level composition.
