application tag on taskbar

hi
when we run any photon application, its tag appears on the taskbar. in
one of our projects i want to execute multiple photon applications from a
photon application. so their will be one parent and multiple childs running
simultaneously. but i dont want the tags for childs to appear on the
taskbar.

how can i stop tag, for child applications, from appearing on the
taksbar?

thanks
