Now in the atlas. Thanks for the contribution

Finally got around to get these into the atlas. Still not the end of my backlog, but at least a solid chunk. Thanks for the contribution.

It is possible, but I don't recommend it. Making a city map on an overland map adds a lot of small details in one spot. This tends to just look like a mess when you are zoomed out to enjoy the overland map itself.

Additionally, city maps tends to get a bit heavy, so adding multiple of them to the same map isn't a very good idea performance wise either.

And you will need to do some manual tweaking regarding sheet setup, since overland maps doesn't have the same default sheet setup as city maps.

Instead, I recommend you use a regular city symbol and map the city as a separate map. Add a hyperlink to the city symbol instead, so you can click it to go to the city map.

A lighter and better way of making a city on an overland map is to actually combine multiple overland city symbols. This doesn't give you the same fine control over houses and streets, but it still look like a city, similar to these maps here:

Looks nice, but I am not sold on the fields here. They look a bit out of place.
