Probably you misused the Megafunction term.

A megafunction is programmable by the user.

You probably need a hierarchical design.

If this is the case you can design your demux using schematic and logig gates and then convert it to a symbol that you can use in your top level schematic.

The same can be done if you degign your demux using Verilog or VHDL.
