Adding a Custom Building and Quest to an Existing Map: Is It Possible?

[noname835]

Hello, I have a question. On an existing map that is 50 days old, is it possible to add a custom building and, most importantly, ensure that its quest works? If, by chance, the merchant does not offer the quest for this custom building, would it be possible to make it available on a scroll or through another solution? Thank you in advance.

Even tho a20 still relevant
As for questing that is upto the game to choose  but it should be questable if the rng sleects it
