I'm looking to make a street name index in ArcPro, but can't seem to find any information about it. There are methods described in ArcMap, but I would be interested to do this in Arc Pro. Thanks for your help!
The new features of Pro are rolling out today, but in previous version the data driven pages and cartographic tools like
http://desktop.arcgis.com/en/arcmap/latest/tools/cartography-toolbox/grid-index-features.htm
weren't available. So just keep using arcmap until the new help is searchable.
There indexing tools for a map series are in the new Pro 2.1, from there, you will need to create a map series.
