Make multi-attribute symbology available in Pro.
Example of desired result: points represented as different sizes per numeric field and different colors per category text field. There is currently no obvious way to achieve this result from the Symbology menu. It can be somewhat achieved via Unique Values and Vary Symbology By Attribute (Size); however, there seem to be a few limitations when compared to the ArcMap method. Namely, the ability to classify does not seem to exist (see the attached screenshots).
Adding the ability to classify (based on Natural Breaks, Equal Interval, etc.) would be a great improvement, and so would allowing the user to change the legend item names (i.e. the values are currently not rounded to whole numbers).
