Whitebox Package File Hierarchy

Is it possible to configure files uploaded to the Whitebox Packages >> Payload tab so that - uninstalled - the app will appear under \Applications as a single file, with all ancillary folders only visible after the ‘Show Package Contents’ file option is cued?

At present, whether I drop ancillary folders under the >> Payload >> Applications folder or under the >> Payload >> Library folder, unwrapped the ancillary folders appear as separate items under \Applications.

So, say I have an app called:

New.app

and a series of ancillary folders called:

\Demo
\Import
\Extensions

I’d like the file:

New.app

only to be visible under \Applications, and the folders, \Demo, \Import, and \Extensions to be visible only after I cue the ‘Show Package Contents’ file option.

Thanks in advance for any advice.

Regards,
