M Syntax for Importing multiple tables from single DB
You won't really be saving much. You'd just have a TON of calls in one model vs a few calls in many models.
There are ways to optimize by publishing certified data sets, or using Data Flows to sync and then using those as the basis for your Power BI models. The latter might be the best, but you'd need someone to set up the right type of data flows to ensure all relevant data is published for use. Then you could have those refresh 2-3 times a day, or less if not needed more often. Then it wouldn't matter if a thousand Power BI models hit the Data Flows 7-8 times a day. Your internal server wouldn't be impacted by that.
