I was trying to create a mapkey that would auto-create default axis for a part. In order to do so, I needed to have them before the regular features in the model tree.
I was getting crashes with some of the techniques I was trying. I found EDIT>Feature Operations>INSERT MODE which I was able to use for part files. However, I couldn't do this in an assembly because INSERT MODE is only for Component Operations, where you can only activate the insert mode after a component not a feature (like one of the default datums). This functionality is absent from Feature Operations. Please include it in Feature Operations (it would then not be necessary for Component Operations as well).
