Copy Product combination to Different Category Product's

I would like to copy and paste product combination only, so for example I would like to copy one product combination and paste it to 10 products on different category's Product.

I know how to create Mass Combination, the problem is when i go to new category product's i need to re-select all the product combination and have to enter the values ( Prices) this will take ages due to we have nearly 50,000 products and 28 colors and 55 product sizes. so cant always use the product mass combination.

Need a simple way to copy the Combination and past it to other products and other category product's.

I dont mind to use SQL or Copy and paste...
Please let me know
thank you for your help
