SHORTCODE for custom categories..

because of the many functions that don't.. we have many manual workarounds.
As suggested here we added yet another category to events categories to allow shortcode display of relevant calendars..
This has now destroyed the CATEGORY COLOURS which is also needed..
meaning we have to yet again go back and redo every single event..

Really tiresome..

So to be clear.. We NEED a shortcode to allow us to use CUSTOM categories or a way to TURN OFF category colours for those that we have to add to find ways round displaying events..
