Symbol Generation with External Text Editor - How to?

Hi,

I would like to use an external editor (Vim) with Quartus. I have successfully configured Quartus to use an external editor but I've noticed that with this enabled, It is no longer possible to use:

File > Create/Update > Create symbol for current file

I believe this is because Quartus thinks the current file is whatever BDF file happens to be open in the background, instead of the actual VHDL file open in the external editor.

I know that it is possible to use TCL scripting to generate the symbol file:

quartus_map <path to project> --generate_symbol=<path to vhdl file>

Before I waste my time trying to script all this from within Vim does anyone know of a work around or perhaps something I've overlooked?

Thanks in advance.

Details:

Quartus 9.1 (legacy reasons for not upgrading to Q11) but can try Q11 if necessary
