Changing (filter) the list in LFG frame (GroupFinderFrame)
 

I want to make some changes in the groups list of the Group Finder frame (find only specific groups according to my wishes). Can I overload groups list loading functions or make changes manually (in my add-on) to existing list, or I can only create my own frame and repeat the functionality of the standard frame (from the exported game data)?
If I can, then what I need to do?
