Linking existing products to a combination (module?)

[Rubycube]

I've posted earlier today as I am having problems with syncing from my inventory program - ERPLY to Prestashop.

 

It imports each of the matrix products (combinations) as seperate products which is making the website messy and hard to navigate (www.rubycube.com.au).  If I ignore the imported products and generate combinations through prestashop I will not be able to synchronize the quantities available.

 

Does any one know of a module or a way that I could link/select existing products to form part of the combination?

 

ie.  I have a product L.E.D Dog Collars [DC] and combinations (12 variants) have already been made in my inventory program.  Currently my website shows each combination as a seperate item.  I would like to somehow link the child variant to the parent (so it still maintains it's code and individuality as a product) but only the parent is listed on the website which drop down boxes to choose size and colour.

 

I hope this makes sense?

 

Thanks,

Jade
