Save Individual Print Settings

Change of an individual item value in custom PRINT SETTINGS (example: changing skirt height from 1 to 3) creates 2 symbols next to it: a 'DISK' and a reverse 'LOOP'. Clicking either one resets the value to the default - a redundant and unnecessary behavior. One of them (preferably the 'DISK' symbol) should make the new value the default for that particular (custom) print setting. Much easier for one changed setting, than checking all the other settings for desired changes, saving, renaming, blah, blah, blah!
