STAAD - EUROCODE WIND GENERATOR FOR DUOPITCH ROOF STRUCTURE

Hello

Does anyone have a code or a macro to generate wind loads automatically in STAAD using Eurocode 1991-1-4 for a long duopitch roof structure ?  

I only have the IS875 in the drop down options for 'Wind Load Generator'. I tried to apply the IS875 and then modify / input my own EC coefficient factors instead, however, this doesn't include the roof structure in the generator, Only the walls.

Regards
