Sync over preferred network

Feature request - Automatic sync on preferred network. 

So here's my situation. I currently use Plex Sync to store locally my media I wish to watch whilst at work on my lunch breaks. My home WiFi is unlimited whereas my work WiFi at work has a data cap. I've noticed Plex Sync will run even when I've cancelled it meaning transcoding happens on my server and then the content is still downloaded and synced over my work network to whichever device I happen to be using at the time. Obviously this is eating into my data cap at work and is not good. My request is for an option to automatically sync when on a preferred or pre-specified network and not to on any other by default. I'm sure there are more scenarios where this would be a good feature for others but this is mine. Others have similar requests on another thread I have.
