There are certain things that require the VI to be recompiled, so they cannot be carried out on a VI that is executing or reserved. To change this will take lots of work and may happen, but I wouldn't wait for it. If you will be running the VI in a development system and not an EXE or DLL, you can look at using subPanels or dynamically loaded panels that are edited using the legend properties when idle and then shown to the user.
