Configure a different service for printing

Hi All

We are using an image MapProxy (WMTS) service that uses a tile on demand strategy.  While some areas are seeded (pre-cached), many rural and remote areas are only pre-cached to level 13 (~1:150000).  The first visitor to a new location is wearing the delay in creating the new tiles.   

While new tile generation typically finishes in under 10 seconds for a screen view (about 20 tiles generated), server load and internet access speed ( can cause timeouts). 

This is causing an effect where some prints are returning with missing tiles, and subsequent prints of the same region slowly return more tiles. What I believe is happening is that the first prints are timing out the tile requests before they have been generated, but MapProxy is still generating the tiles in the background.  So, subsequent print requests will start to include those tiles.

What I was wondering is .... is it possible to configure Geocortex to use the WMTS service for on-screen viewing only and use the MapProxy WMS service for printing.  The difference is with WMTS we are making many requests to MapProxy, while with WMS we are making only 1 request and that waits until all the tiles are generated and then combines them into a single image returned.

Note:  I have considered just using the WMS, but due to poor interent speeds in some of our regional offices, it makes the application unsuable.

Cheers
