Is there a simple way to tell whether another user has access to a file with the HCL Connections Files API?

Question

I need to detect whether another user can open a file from HCL Connections Files.

Is there a single request that can be made to retrieve a particular user's access to a File?

The acls=true parameter listed here retrieves access for the current user. Ideally I'd like to specify another userId to retrieve access for.

Otherwise I'm going to run through and check the several ways that a user can have access to a file (Explicit permission, permission via community, library owner, public file visibility).
