Ok so my problem:
I have 3 people I want to track as they enter/leave specific (currently 38) zones I have setup on the map. This let to there being 2x38x3 - 228 - automations. I wasn’t happy with this as it’s a lot of automations to manage and a complete pain to deal with should I wish to expand the number of zones or people.
As each person enters/leaves a zone I wanted a notification on my mobile and/or an audio notification on alexa.
My solution:
I have created 3 blueprints that allow you to choose if a person will generate a text, audio or both types of notification. This allowed me to reduce from 228 automation to just 3 - 1 per person. I have however setup 1 of each type per person with 2 of them turned off so that I can easily switch between the 3 types of notification. I can now add as many more zones as I wish and dont have to make any changes to the automations 
I’ve decided to share them here as they are the first ones I’ve created and would like any feedback on how they could be improved or for you all to use - I know as a novice at this how much of a pain it was to figure this out so it’ll hopefully help someone here too. I’ve added comments so you can follow what each part does.
Tweaks I would like to make:
I’d like the ability to have this as a single blueprint where you can choose multiple people/outputs but due to limitations each box isn’t optional in the triggers/actions section at the moment.
I’d like to have services selectable from a dropdown - currently for the audio notification you have to manually enter “notify.alexa_media_my_echo_dot” as text for “notify_device_1_1” (audio) or “notify_device_2_1” (dual)
My code:

** See below for the other 2 versions of the blueprint - as the “import blueprint” function will only import the first blueprint in a thread the other 2 versions will need to be imported manually, this can be done using visual studio code/samba or any other method you prefer **
