Questions around new 24D feature of user defined holds in Payables

Summary:

Does the feature defined in Overview of User-Defined Holds leverage the same operators as referenced in Manage Workflow Rules Using a Spreadsheet?

Also, what are current plans to enhance the available fields for selection? For instance, will invoice creation date become available for selection in future releases? We currently have an extension which will release a manual hold (placed on invoice import) two calendar days after the invoice is imported where we are leveraging invoice creation date. This feature could potentially eliminate the extension but wanted to see if fields and an operator like " TRUNC(Invoice Creation Date) less than or equal to TRUNC(SYSDATE) -2" would be available for use sometime in the future.
