This is in our backlog. Please vote to receive updates as we make progress.
Another update on this item – users now have the ability to set up scheduled subscriptions with paginated reports and 6 different formats, along with parameters per subscription to allow further personalization. There is also now the ability to create paginated reports against any Power BI dataset in the service, and we’re planning to add drillthrough from Power BI to Paginated Reports in the short term.
We still have plans to support e-mail attachments for Power BI reports as well in the coming months, and we’ll share more specifics once we get closer to starting that work.
We’re pleased to announce that in the May release of Power BI Desktop you can now define incremental refresh policies for your models.
At present these only apply once the model is published to a Premium workspace in the Power BI service; we’ll be bringing it to all Pro users in the future.
You can read more about it in our blog here: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-may-2018-feature-summary/#incrementalRefresh
We’re going to leave this idea open for now, so please give us your feedback while we’re in this preview phase!
