I have 2 daughters ages 5 & 9 and even with the volume modes they have a issue with hearing it and we have a 64" Element Roku TV none of the modes are set for children's TV programs so they are always turning the TV way up would it be possible to get a update and add a max volume lock so the parents can set a max volume level they can't go past ? My wife and I would really appreciate it more then you know thank you for your time.
