FSDEM: when a possible upgrade?

From a paper map with scale 1:100000, find points of Trigonometry (GRADING POINTS / POINTS OF SUPPORT: THEY ARE CHOSEN IN POSTS WHICH ALLOW A GOOD VISIBILITY IN A WIDE RADIUS. ARE CHOSEN WITH CARE AND RECORDED WITH SIGNIFICANT ACCURACY. ), Then the altitude of much more precise value of the DEM (SRTM3 version2). :( Well you can with FSDEM through Operations \ Elevations Value Change "You can replace by any other value every occurrence of a specific elevation value, on the whole mesh or on the current selection. Enter the original and the new elevation values in their respective boxes. The program will replace all occurrences of the original value by the new value. " The problem comes when you need to do this. :( - There is no easy way to get to the point of change if not manually find the coordinates X (Long) / Y (Lat) .0,0 -: - 1200.1200.- With the selection rectangle to a point the change also affects all other points in the rectangle of the graphics if they have the same value as the one we tried that is at the center of the selection.Would it be possible to change the program? However, thanks to Emerson de Oliviera for this as it is.
