Default attributtes (color, sizes) for all products?

[Tonimito]

Hello!
I'm looking to create preset attributes in virtuemart. I want to get a list of features appears on all products in my shop without having to specify individual product to product. For example:

- Size
--- S
--- M
--- L
--- XL

- Colors
--- Red
--- Green
--- Yellow
--- etc, etc.

I want to set my sizes and colors only once and automatically appear on all my products to the store without having to configure them one by one.
Is this possible? How?

This plugin is about the solution, but not automatically added to all products, should be done one by one.
But anyway thank you very much!
