So I am running Waterdeep: Dragonheist for my group and the book can sometimes be ague when it comes to downtime, neighbors and villains. However, I have found that there are several official posts about Waterdeep: Dragonheist and the topics I have listed above that are extremely helpful to me as a DM to use in my campaign. Would it be possible to link existing posts (and maybe new ones as they are posted) to the digital sourcebook itself for easy access? I feel it is an obvious upgrade compared to the physical copy and a great quality of life improvement for DMs.

Official posts? Like what?

I am referring to the posts that you see on the Home page that get updated every now and then.
