I start with that I know nothing of modding and I don't know if this is even possible in this game's engine... BUT I wanted to suggest an idea and if its already a thing then great! Please tell me where to find the mod

So basically my suggestion is this:

To be able to able to expand domes like that of lets say "Jurassic World Evolution 2" with the lagoon or bird cages. Where you can place them side-by-side to create a bigger dome.

I know there are different size/shape domes already, but I'd like to build a big capital-sized dome... and yes I know there is one of those, but its limited. I'd like to expand on maybe making a long dome with sections of large patches/pockets of domes maybe going around a out-side garden or lake estate.

Again I don't know if its possible in the game's engine, but would be cool. Dunno how well that'd work with the trains or depots and what not for resource transportation... just a thought though.
