Multiple Categories in csv export

In DP the csv export for categories included all the categories separated by comma’s.
In RDT the csv export for categories only includes the first category.

Is it possible to include all the categories, chosen for the listing in the csv export with some kind of delimiter between them?

I am fine if the import only includes one category as far as when the initial population of a site is concerned this is all that is needed. In our case we need the export data to reflect all the categories as we are using it for an associated print directory.
