Environment Specific Constants - Any plans to allow us to flag "multiple", or non-primitive types (i.e. Appian object pointers like Group, Process Model, etc.) as environment specific?

I am using a modified version of the LDAP Sync tools application that we are using for synchronizing users in several different environments. (See LDAP Synchronization) Rather than forcing an administrator to modify the configurations via the Tempo Action every time a new version of the application is imported, I had hoped to set the filters to be "environment specific" constants. To my dismay, I discovered that environment-specific constants are limited to only primitive types, and not arrays. (This means the grid of filters cannot be environment specific, and the Appian groups synched also cannot be saved as environment specific). 

I believe this is a valid use-case, and was wondering, are there are any plans in the roadmap to enable us to mark more types of constants as environment-specific?

Thanks!
