try using the command ed executing from workbench/execute command or via shell:
example:
ed dh0:games_drawer/first_game
it creates a empty text file and allows you to edit it,
then you do some commands like your startup-sequence:
stack 16000
dh0:games/sokoban/asokoban
then you save it, open this drawer,select window/show all,
select the icon first_game and then menu icons/properties,
you set the icon as project and in the "icon" label put "c:iconx" as
default tool.save it and,well,your first drawered shortcut

later you can change the icon`s image.
