How many functions in your local?
If 'small' then use Search Large Properties - Stella Tools (CA Plex Developer Tools)
You need to search for 'ROUND=' and once the list of functions is displayed you can then create a list. Then you can drop the list into G&B window restricted on language winc! You can then drag and drop this on to another list to create a list of just winc.
If 'large' then use Export Large Properties - Stella Tools (CA Plex Developer Tools)
Basically see the videos and help text. What you are asking is EXACTLY why these tools exist
If you want the list now then contact me and I can do it for you now
