The issue with trash could be solved if trash bins could be tagged in a workzone like facilities...
Yes, I was thinking this as well, so that Caretakers have more objectives to check off.
However, it wouldn't really be all that necessary if they were just programmed to know of the existence of all bins.
They might be, I'm not sure, it's either that or they only get triggered when a bin is within a certain radius of them (which I bet is the case), but then I'm not sure if perhaps their attention to them improves with more training. - That would be nice...
Otherwise, yes, if it would improve the management of bins, I'd also like to see the ability to just select them in Work Zones. This feature already exists anyway and I find it to be underutilized in terms of things you can select.
