option to take WP altitude and speed from previous WP

[twistking]

I would like an option where you could just leave altitude and speed settings blank and the editor would take the values from the last WP where thsoe were defined. that way you could set up a whole route or route segment and only need to change one WP to change the whole segment's speed and altitude settings.
for example if you canged the weather and wanted to adjust altitudes of AI units to clear the clouds, you would only need to change a singel value per group.
