Need Deep Dives

Many classes do a pretty good job of giving instruction on a broad topic, but I find that the information is gone over quickly without much depth. There needs to be more deep dive topics. For example, I am an Azure administrator, and a deep dive into all the ins-and-outs of an Azure Firewall would help me more rather than mentioning the firewall in a broader scope and then my having to do more and more research to find the information needed to actually use the product.
