There's no size column in the "import template".

But I have shoes that the sizes are with "Y" behind the actual sizes.

For example, the "Air Jordan 1 MID (GS)" has US size of "4.5Y", I can also use the EU size "36.5".

But is there a possibility that I can use both of them?

I have tried to use other columns "Price" "Weight" and "Description". 

Only "Description" column works because the descriptions is only for details.

The other 2 columns don't work because they can only contain numbers.

My goal is to scan the EAN and get the result directly with US size and EU size and its stylecode.

By the way, each size has unique EAN on them. So it should be easy to accomplish.

But I don't know how, please give me a direction.
