One more idea: since this is just for display, you could use "Volume Tracer" to place "markers" (which are essentially fake atoms) interactively in space. Although it is called volume tracer, you can place markers in space independent of any volume data.
menu: Tools... Volume Data... Volume Tracer
in that dialog's Mouse menu, turn off all settings except turn on "Place markers outside data"
... then proceed to place markers interactively. You can move them around, change radii and color, etc.

>> Much Thanks!
