Can I switch to my custom Function category ?
 

I have written an add-in using the Excel C API (not the COM API)

I have created my custom function category, that lists all the
functions available in the add-in.

The add-in also adds its own menu to excel, where i give the user a
way to call up the Insert Function dialog.

When the user chooses this Insert Function from my menu, can i
automatically switch to my category?

-Thanks!
