how to calculate least cost path between all points

I have a dataset of 34 sites, and need to calculate the least cost path of each site to every other site in the dataset.
I have managed to successfully run a model, however because I am using the same site input file for both site origin and site destination, the least cost path is each site to itself.
Is there a quick way to tell arcgis to not calculate the distance of a site to itself?
I am using arcgis 10.1.
Any help would be greatly appreciated, as I don't want to create 33 dummy destination files, with each origin point removed.
