Install SSH and learn a few linux commands if needed - chmod, chown, etc. It will do what you want and save you hours/years.

again i seem to have communicated less than precisely. my understanding is extremely limited (i have no formal computer training or programming experience) when i asked about researching Linux, it was in reference to understanding the permissions parameters offered in Raidiator (the {?} boxes merely restate the titles - and there is zero documentation that i can find). a quick search on SSH intimidated the bejesus out of me...

One option you have is to set things up so that everyone saving files to the NAS is using the same NAS log on... you can set this in the Credential Manager in the control panel.

if i make everyone a single user won't i lose all of the dedicated user shares and the ability to keep private data? or is there something in credentials manager that would allow selected users to share credentials only for selected shares?

what i seek is that ability to fully share read/write authority of data in the Media share with a specific group - but still be able to use personal and public shares for other data and groups. is that not possible with this technology?
