Need To Add Subfolders To Existing Folder Structure

So basically I was wondering if anyone could help me write a script doesn't matter if it's in the CMD or powershell but what I need to do is add two folders with sub folders to existing client folders with in an existing folder structure with working files from over 10,000 clients.

The basic folder structure looks like:
F:\A\ClientName\
F:\B\ClientName\
and so on
Then a bunch of sub folders as per screenshot (Note in screenshot I wasn't using a networked drive as I am testing on my personal laptop)


So what I need to add to the first folder ("ASIC - Company Secretarial") in every client from A-Z is two subfolders with folders with in them eg

Company Register
Company Register\Asic
Company Register\Misc

Trust Register
Trust Register\Asic
Trust Register\Misc


That is just an example but I will be given the sub folders to be added very soon.

So is there a way to write a script which will go through to every folder and sub folder to add the new folders?
It would take a very long time to do it manually as they have in excess of 10,000 clients.

The folder structure is set up for their current software management system, from what I can gather it was custom written but works well to set up a new client folder, so new clients isn't an issue.

All I need is to add the folders and sub folders to existing clients in the sub folders.

Does anyone have software or help writing a script to insert all the new folders.

By the way if there is software to do this I will be happy to use it if it is easier

 

Update: got a working script
