Updating GROUP ATTRIBUTES using Customization File

Hello Appian enthusiasts,

I am trying to improve an internal deployment process, and one thing that pop up is the need to update "Group Attributes" in every environment, because we are using SAML Sync.

I know Stefan already published an awesome article proposing a solution (SAML Group Sync – Appian Rocks). However, it is for applications starting from scratch. In my case the pieces are already setup. Then, I couldn't find in the documentation a way to use the Customization File for that (Managing Import Customization Files - Appian 24.2).

Is there a way to update the group attribute during the deploy or am I asking too much from the Customization File capabilities?

Thanks in advance for all!
