Does Global Mapper have any future plans to allow terrain export at multiple resolutions?

Let's say for example I have a 1 foot resolution lidar data set. I would like to only keep the 1 foot horizontal spacing resolution for only a few small select areas on my terrain, the rest I would like it to be something like 2 meter (trying to get some areas of the terrain mesh to have more detail, and other areas less detail). So first, I would need to be able to make selections on my terrain mesh that I want to keep at the 1 foot res. Then when I export the entire terrain as a single mesh (which I usually crop to selected feature) it asks what resolution you want to export as. There would need to be multiple export options where it retains the 1 foot data on the selected areas and the unselected areas you would enter a different resolution. Can this be done? I'm sure it can be, I work with terrain elevation all the time and we can have some areas at different grid resolutions than others. 

Anyway, thanks.

    You could export the selected areas out as an XYZ Grid at the spacings you require. Them import both points files back in and GRID them together; checking the option to Save Triangulation Network (TIN) as a Vector Layer. You can then export the hybrid mesh out if required.
