[NTG-context] ConTeXt-mode and AUCTeX

I recently switched from context.el to AUCTeX 11.55, with "built in context-mode". One feature from the original which I am unable to find within the AUCTeX version is the automatic prompt (open square bracket) for arguments with every \start... \stop... pair. In original I used C-c C-o (tex-context-block), in AUCTeX, I'm using C-c C-e (to insert any \start \stop pair), not the same command, but the original doesn't seem to be available. Is there a way to get the automatic prompt for arguments? Thank you --
