Replace container size icon with just a letter

Hi,

currently the container size is shown in different rectangular boxes in different sizes with the letter "S" in a round shape before the size.

What a bout to replace this to a single rectangular shape which contains just one of these letters: M,S,R,L,O,U

This would save space for other information and it is easier to read. I often hear from friends what's the first size that locus mentions is it micro or other?
