747 Queen of the Skies and Ch products MFP

Does anyone have any ideas about how to get the MFP to operate aircraft controls that don't have a direct keystroke command. Most of the MCP/EFIS controls have a direct keystroke command, however I would like to setup the MFP to control the FUEL CUTOFF SWITCHES, ENGINE FIRE SWITCH and BOTH ENGINE FIRE BOTTLES. These controls have no direct keystroke command in either FS2004 or PDMG, the only way to operate them is via mouse selection. Is the a way to program the MFP to select the overhead panel then move the mouse pointer over a control then operate that control via a mouse button selection.Thanks in advance.
