MATLAB: Is there a way to see the Library Link Display for a masked subsystem with an invisible frame in Simulink

displayinvisiblelibrarylinkmasksimulinksubsystem

My library contains masked subsystems. The Frame property for those subsystems is set to Invisible.
I would like to be able to see if the block used in a user model is linked to the library or a local copy. This is easily done with the Library Link Display option in Simulink.
However, if the Frame setting is Invisible, the library link display does not appear.

For a masked subsystem, the link display will only be shown if the Frame visibility is set to 'Visible'.
A workaround is to add a line to the masks in the library:
text(.2, .3, ['Link Status: ' get_param(gcb,'LinkStatus')]);
See the attached example library. Drag the block into a model, and the Link Status will show 'Resolved'. If you right-click>Link Options>Disable Link, after an update diagram, the display will change to 'Disabled'. If you then right-click>Link Options>Break Link, after an update diagram the display will change to 'None'. Note the display is 'None' in the library because that is the original source of the block.
