Fantasy Regional - making parts of what is already there

Why cant we get singular stamps from things like “Abandoned Graveyard”?

Right now there are no tombstones in Fantasy Regional, why cant I get a stamp (that you already have the texture and everything for) out of the “Abandoned Graveyard”?

Also Fantasy Regional is missing so many basic stamps like: Animals, a Church, a Gatehouse and so many more I dont even know about yet…
