Multiple Similar Bluetooth Devices

Hello all,

I am curious to know if anyone has an efficient way to managing multiple bluetooth devices on their iPhones, particularly similar bluetooth items. Here's my exact household scenario:

I have 3 Bose Soundwave Minis in different areas around the house and bring with me to work, a living room stereo system using a a logitech bluetooth receiver, a bedroom stereo using a similar receiver, a stereo in my backyard using Roverbeats Unify bluetooth receiver, and another in my garage with a similar Roverbeats receiver.

Often times with the receivers, my phone will connect to a receiver in the other room despite literally being in front of the receiver I wish to pair with. So I am often either having to choose between keeping the receivers I don't wish to use unplugged, or selecting "forget connection" on my iPhone each time and just re-pairing. With the Bose Minis I have not found a way to rename each different unit which is confusing since they are all labeled the same in my Bluetooth connections list (I am able to rename each unique unit on my Macbook but will often still get confused and have trouble connecting, causing me to have to forget all connections with all the minis just to reconnect from scratch). I have each Mini labeled with A/B/C but don't have a way of differentiating each on my iPhone.

So essentially i'm constantly having to forget connections and/or keeping certain receivers unplugged. Has anyone found any simplified bluetooth utility feature to make renaming/prioritizing connections? I have an iPhone 5S 9.3.2.
