7-zip - Looking to zip sub folders but not all sub folders

Question

I have a folder structure of:

-MAIN
-- Branches
---001
---002
---003

I want to zip 003 up so I have a zip of

-MAIN
--Branches
---003

I'm using:

7z a "C:\My Files.zip" "C:\MAIN\Branches\003" 

But this gives me a folder of just 003 in My Zip without the folders before it.

Any ideas?
