Add button "Create group" in Characteristcs

When i have many item in each of characteristics - i can't create only these item, wich i need.
I can create all items of all choose characteristics, but i need half of all items.
Function of button "Create group":
1. Show window with checkboxes of all posible items and choose only half of all items.

Sorry for my English - i'am from Russi

You need to click on the "manage variants" button when you edit a product. There, you can select which variant to use and which to not use by publishing/unpublishing them.

Ok. I click on the "manage variants" button when i edit a product. There, i select which variant to use and which to not use by publishing/unpublishing them.
Later i need add also 100 variants. And i must 100 times click "Add/Create". That is right?

Indeed. Another solution is to delete all of them, delete the characteristics from the product, save the product, add again the characteristics and all the variants will be created automatically again and you will have to publish/unpublish them again.

"delete" - realy funny.
This is only proposal for developers
Component - realy cool, but need work on it
