How to share several files and folders with one single link ?

Hello,

we would like to share several files and folders with one single link.

Like if it was a virtual folder including grouping several files and folders archived elsewhere.

How could we proceed ?

Exemple :
Our server has the following folders :
C: / Sales / invoices
C: / Technical / datasheets
C: / Marketing  / Pictures

We want to share to customers the folders : Invoices + datasheets + Pictures with only 1 link.
We don't want to copy/paste those folders in a "New folder" otherwise we would have 2 versions and files would not be up to date.

Is it possible to automatically synchronize content of one folder into another one ? If we can automatically copy the content of our folders in a "new folder" , we could only share that folder and content would be up to date.

Thank you !
