One Flag CTF Question

How do I make this possible?

I want to make the game with 4 teams fighting for one neutral flag that any team can take. Thought it would be easy enough but then when is it ever.

I have one Flag Stand with these settings:

Team: Neutral
Game Specific: True
Game Type Label: CTF_Flag_Return

It will not show in a match so I am confused. Is it that I have no place to take the flag too?

All tutorials I am finding are for setting up at least two flags so ANYONE that can shed some light on this issue would be of great help.

Anybody got any answers?
