Advertising signs and signposts without function?

[Rusty2000]

There are so many improvements in Planet Zoo compared to Planet Coaster, but why is there no possibility to make promotions to attractions or enclosures on advertising signs or signposts? That was a very cool thing to get more visitors at certain locations...

This could be really cool. Maybe it would help to distribute the Guests better throughout the Zoo, so the Trash cans aren't already full after a few Minutes.
Oh my God. How awesome it would be if we could also advertise Areas without Enclosures. When I build Plant Houses they are always so empty

You can sorta fake it by hiding education boards/items in something (so long as there's some animal nearby to activate the board), or - if the object is big enough, things like ATMs or etc. I made a fake first aid station that I hid a toilet in so guests would go in.
