More simultaneously connected Bluetooth devices

Currently seems to be limited to 3. For example, when i have my heartrate monitor and both handles, i can't connect the ring - says the maximum number of connections has been reached. I have to disconnect a handle to enable the ring. I would like to be able to have both handles (since i could be reversed on some exercises, even if i always enable the weight with my right hand), plus my heart rate monitor, plus be able to use the ring when switching to an exercise that uses a bar. all without having to re-enter setup to disable something.
