Inserting horizontal bar into the start menu

[csicsi]

how can i insert horizontal bar or comparable dividers into the start menu's customazable section?

i press "start", then a one (1) column menu comes up, on the top of the list, is a folder where i have the shortcuts of my most often used 20 or so programs (this opens to the right as an another column). how can i place dividers here so organizing similar programs in a gorups (prefer not to use sub-folders)?
