ebay listings with variation is full of blunder !

[uniwarehousewares]

listing with variation require item specifics for sizes but there is no option there to put multiple sizes in item specifics for diff variations  and as result you can't revise the listing  with multiple sizes in item specifics, what a poorly design . example if there are 5 items with different sizes in one variation listing but item specific only allow to put size for one instead 5, if you put size for one, that is confusing for customers. 

is any body facing same issue with variation of listing?

Do you sell various sizes of the item in the variation listing?

Do you have different colors?

What is it that you need the variation to call out?
