It does exist for the Premiership, where one fan per club is part of the Fans Voice group, which meets periodically with Phil Morris.
Some of the reps have gained some traction with their own clubs promoters
There is also a rep on the group who does not represent Premiership clubs, but acts as a rep for feedback from other clubs and defunct clubs. The group that that rep comes from contacted all other clubs and got zero respone. However, they collect views and ideas from fans on the groups Facebook page and submit those monthly or thereabouts to Phil Morris.
At last years AGM Phil presented the document, which had 1600 lines of ideas and comments. Regretably the fedback from AGM was almost non existent.
Ideas have again been summarised and submitted throughout last season, with no feedback at all.
It's difficult to help promoters when they simply wont engage.
