EPM User group management via integration from source system

We are planning to maintain our user group within EPM to maintain current status and security in line with our source system through EPM Automate and an internally maintained file transfer system. To do this, we are using the assigned templates for user provisioning (examples attached).

Per the structure of the templates that assign groups, each group must have an individual file with the names of those assigned. In the case of specific organizational security, we have roughly 96 active groups which users will be assigned.

If we managed to maintain user access on a daily basis as we do with other systems we operate, we would be moving over 100 files daily, along with general user access and global groups all users are assigned.
