At ArcGIS for Server 10.1, there is a print task installed by default.
Looking at the web-help, it states:
The PrintingTools service included with ArcGIS for Server references a preconfigured folder with 8 map layouts. These include basic designs in the 8.5 by 11 inches, 11 by 17 inches, A3, and A4 paper sizes in both portrait and landscape orientations. If you want to use your own layouts, you can publish your own service for printing web maps
Despite this advice, I want to confirm if it is possible to include additional templates to this Out The Box service, as opposed to having to publish a separate service.
Looking at the Service in REST, I can see these templates.
I also found the corresponding templates under:
C:\Program Files\ArcGIS\Server\Templates\ExportWebMapTemplates
If I drop a new 10.1 MXD into that folder, and restart the PrintingTools service (which now automatically clears the REST cache at 10.1), it will not pick up this new template.

Is there any way to configure the underlying GP service behind Export Web Map to accept new MXDs?
I did notice that if I edit one of these existing templates (e.g. add a North arrow) then these changes flow through.
