Default Size Guide for all products from smallest to Largest

Please for the love of God, can you not sort the Clothing Size guide to show the international standard of Smallest to Largest rather than just saying do it manually..... (Over 600 products, you expect us to do it manually!)

Clothing internationally is sorted like this S, M, L, XL, 2XL, 3XL etc  NOT like your system currently has them ordered: 2XL , S, M, L, XL
