After using simbrief downloader with X-Plane for a good while I noticed that sometimes, especially in the G1000, altitudes that are imported as a part of the flightplan tend to interfere with VNAV since it treats them as altitude targets. They cannot be deleted from in-sim, only overriden with a different altitude. Chaning them manually in the .fms file solves the issue, but it is tedious. Could we get a new format, X-Plane 11/12 (No altitudes) similar to how we have the No SID/STAR variant? The only change needed from the existing format would be ensuring that every waypoint except ADEP and ADES have the altitude as 0.000000
