Google Products For Multiple Categories

-- url of the page with the problem -- : drc144k.com/
-- HikaShop version -- : 2.2.2
-- Joomla version -- : Tried on 2.5.14 - 2.5.16
-- PHP version -- : Tried on 5.2.x thru 5.4.x ... same problem.
-- Browser(s) name and version -- : Firefox, Chrome, Opera
-- Error-message(debug-mod must be tuned on) -- : NONE

We wrote custom code to handle multiple categories submitting to Google Products on top of HikaShop 2.2.2. In the latest version I see there are fields for categories, age, gender, etc added to the admin. Luckily updating to 2.2.3 and/or 2.2.4 did not overwrite our custom code so the products are still submitting to Google properly.

I would love to remove our code and use HikaShop code only. Is it possible to submit products from different categories, different colors, different sizes, etc to Google? Or would we still need to have custom code in the plugin to handle that?

Ex of what we submit with our custom plugin code:
PROD1-UPC,T-Shirt, White, S-M-L-XL, Adult,Men
PROD2-UPC,T-Shirt,Yellow,S-M-L,Adult,Women
PROD3-UPC,Jacket,Gray,L-XL,Adult,Unisex

Is this type of submission possible with Hikashop 2.2.4 version of the Google Products plugin? If so, what's the syntax/setup we need to do?

Thanks.

Excellent!! It appears you used the same logic we used AND you made the admin piece for it. Great job!
