Alerts for High/Low Outpost Stored Product

It is easy to forget that workers are assigned to a mining outpost (such as a coal mine) that isn't currently being used and the stored product buffer is already full.
It would be nice to have optional 0%, 25%, 50%, 75% 100% alerts for outposts in the same way they can be assigned to storage buildings.
Another possibility could be to have assigned workers automatically scale up and down based on demand.

Great idea, all too often ya cut back on diesel production and forget to scale back world map oil rigs ect. Plus 1 for alerts on world map production locations.
