FVWM: Expand Stalonetray in Right Panel

I sometimes have more than seven items which want to place an icon
image in the stalonetray.  However the tray will only show seven icons
in the 120 column width of the right panel. Using the standard
Right-panel how would one change the stalonetray to a second row of
icons?  Is it simply a matter of changing
$[FVWM_DATADIR]/default-config/.stalonetrayrc
Max geometry to 6 x 2 or is it more complicated?

Current code from RightPanel: 
*RightPanel: (120x5, Frame 0)
Test (x stalonetray) *RightPanel: (120x20, Swallow(NoClose,UseOld) \
    stalonetray 'Exec exec stalonetray --config \
    "$[FVWM_DATADIR]/default-config/.stalonetrayrc"', Frame 0)
Test (x stalonetray) PipeRead 'echo "*RightPanel:
(120x$(($[vp.height]-225)), \ Top, Swallow FvwmIconMan \'Module
FvwmIconMan\', Frame 0)"' Test (!x stalonetray) PipeRead 'echo
"*RightPanel: (120x$(($[vp.height]-205)), \ Top, Swallow FvwmIconMan
\'Module FvwmIconMan\', Frame 0)"'

I don't mind if it is always displays two rows,
so no fancy coding necessary to expand if more than seven items.

Advice is appreciated.  Cheers, BrianA_MN
