Getting Page Letter Instead of Number Through Dynamic Text

[NateHauck]

The place I work for has a naming scheme that prevents us from using a map series to produce exhibits of all of the aerials used for a project. It requires us to use the corresponding letter of the alphabet to describe what sub-exhibit it is (ie: Exhibit 5a, Exhibit 5b, Exhibit 5c...). I would love the option to be able to do page letter instead of number to be able to add that bit of dynamic text to be able to automate this process.

Yup. You can definitely get around it currently by messing with the Attribute table of whatever your index feature is, but it'd be nicer to just have letters automatically.

You can accomplish this by entering your exhibit numbers (5a, 5b, etc.) into a field in the attribute table of the feature class that you're using for the index of your map series.

For example, I have an ArcPro project that is a map series, comprised of 13 map sheets. Here's the attribute table for my index feature class:

The individual map sheets are named according to the value in the Index ID field in the attribute table.

The Index ID field is then used as the source for dynamic text for labeling each map sheet.

Closing as already offered. Thanks @Scott_McGee for the excellent explanation and screenshots.
