Offset Attribute Value for Multiple Features

Is there currently a way to add or subtract from the value of an attribute for multiple points?
For example: I discovered that elevations for about 50 points were wrong by 2.8 feet. I would like to subtract 2.8 feet from the elevation of those points.

While there isn't a way to directly do that in Global Mapper, you could export a point Shapefile with the points, then edit the DBF file in Excel and subtract 2.8 feet there, then save the DBF and load the Shapefile back into Global Mapper.
Let me know if I can be of further assistance.
Thanks,
