Private Channels set at 30, need more please.

Now that we are all online, I would like to create a private channel for each school in our district for School Advisory Council (SAC), but we have 45 schools at the moment and 2 new schools under construction and Teams will only allow 30.  Would it be possible to expand the number of private channels in Teams.  It is an awesome tool, Love working with Teams, but I cannot use it the way I need to.  Please advise.
