[Qgis-user] How to combine multiple rasters into a tilesarray?

[Joep Orbons]

Using QGIS 2.14.3 Essen at Windows 10 Prof. 

Being rather new to QGIS but not to GIS, I'm still trying to find my way in the  QGIS system. 
I can "Add Raster Layer" to show a raster. Multiple raster, no problem, they all fit nicely. 
When I select one of the rasters in the "Layers Panel", I can select "Layer" "Save as" as a geotiff with VRT options and parameters. It results in a nice series of tiles. 
But how do I make one series of tiles for multiple rasters? 
I tried "Raster" "Merge" to make multiple rasters into one big raster. But my rasters are large, spanning a huge area. So making them into one large raster is not an option. 
What options can I use to make the multiple rasters into a series of tiles, respecting the order of the files as they are in the "Layers Panel"?

Thank,

Joep
