Feature Request: Support for Multiple Parameters for the Same Property via ADMX

[klim]

Summary:
Currently, when configuring settings through ADMX templates in Active Directory, if multiple changes are applied to the same property from different locations (e.g., different GPOs), only the last change is retained. Previous values are overwritten. This behavior limits flexibility when administrators need to aggregate multiple values for a single property.

Why This Is Needed:
In environments where users belong to multiple groups, administrators often need to apply cumulative settings. For example, mapping multiple network drives or adding multiple network_indexes based on group membership. With the current implementation, each subsequent policy overwrites the previous one, making it impossible to combine settings dynamically.

Current Workaround:
We currently duplicate all required ADMX settings across multiple locations to avoid overwriting. While functional, this approach is inefficient and hard to maintain.

Proposed Solution:
Introduce an append functionality for properties in ADMX templates. Instead of overwriting, new values should be appended to the existing property. This would allow administrators to define multiple parameters for the same property across different GPOs without conflict.

Example Use Case:
A user is in multiple AD groups, each assigning different network indexes or search paths via Everything ADMX.
Instead of overwriting, the system should merge these values so the user gets all relevant settings.

Benefits:

Simplifies GPO management.
Reduces duplication and complexity.
Aligns with real-world scenarios where cumulative configurations are required.

I have put on my TODO list to add support for user-group policies.
Thank you for the suggestion.

For now, Everything only supports Local Machine and User Policies.
