When we are deploying Discovery Hub over and over again, one of the most painful aspects is setting up the Environment Properties. I think there are a couple things which could greatly improve that experience:
1. Ability to clone settings from one environment to the next for a Global Database. If I get the Global Database setup for Dev, it can make things much faster to clone those Dev settings to QA and then tweak the info which needs to change! Right now I usually copy and paste one field at a time.
2. Ability to clone a Global Database to a new one... this would be particularly useful when there are multiple SSAS Tabular Models. Right now I need to manually create a Global Database for each model (7 of them) and manually set all of the settings for those in each environment (21 settings boxes ahhh!)
