PDM - Multiple serial numbers

I've been challenged with the following:

49 folders that each need their own serial numbering scheme. The numbering is the same, a 3 digit counter value. But each folder needs its own unique counter. Example:

(Folder) A320-44

     A320-44-001.doc

     A320-44-002.doc

     A320-44-003.doc

(next number would be -004)

(Folder) E195-25

     E195-25-001.doc

     E195-25-002.doc

     E195-25-003.doc

     E195-25-004.doc

     (next number would be -005)

How can I best achieve this? If I have 49 folders, will I need 49 separate serial number items in the Solidworks Admin tool? Obviously that's not a desired solution. I can just see the right-click menu having 49 options from which to choose. Wow.

Could the user enter the sub-folder, then right-click to generate the next number for that folder? If so, how is that possible - using one serial counter? Or is it not possible? Much thanks!
