For the record, you can do this with ProRaster Essential (or any other variant of ProRaster). You create a "raster source" which contains all of your 30 grids. This can then be displayed using the VCP you require, or any other method. You would then publish this rendering algorithm to MapInfo and it would display in Pro. All of about 30 seconds work.
But this won't work with Pro version 15.
I wonder if a seamless table can be used to do this?
