As I dig through the system - I've been apprised that this option is available.
You can customize LDAP/AD/Azure import up to 5 fields from your User source.
[Setup] > Setup > Custom Fields | Category = Mixed Mode Accounts (or LDAP/ADS Accounts).
Depending on your LDAP import Mixed Mode or LDAP/ADS/Azure the Category drop down relate.
By adding these custom fields you can then manually set the Attribute Mapping in the User Source Mapping configuration.
After configuration of the AD Mapping Attributes, Sync ZSD with your user source.
Those attributes can be used in ZSD searches, views, etc.
