Attach measure to database table

It would be nice to attach calculated columns and measure to a database table. When you import such a table to a new Power BI report, you would also get the calculated columns and measures you previuosly attached to it.
It would also be nice if you could manage these columns and measures in one place so that any update would propagate to all Power BI reports using them.

For example: Let's say you have created a column "dateIsInLast12Months" in your table "dimDate".
This column is true or false depending on the date being in the last 12 months and is calculated using dax. Every time you import dimDate into a new Power BI report, you would also like "dateIsInLast12Months" added automatically.
