FVWM: How to make window appear on multiple (but not all) desktops?

In my FVWM configuration, I can use either Sticky:

    # Show window on all desktops
    Style *Emulator* Sticky

…or StartsOnDesk:

    # Show window on desktop 3 only
    Style *Emulator* StartsOnDesk 3

But how can I make a window appear on, say, desktops 3 and 4, but not 0, 1, or 2?

Thanks,

Stephen
