Is it possible to add flags to a source map using just EntEd?

I would like to make a true dod version of dm_runoff, rather than the deathmatch one I converted which just has dod spawn points.

I have placed the flags using info from posts on this site and they all show up ok but when u run thru nothing happens.

In the old DoD I could place simple rush one man flags (like in Flash) but always assumed that area or 2 man cap flags (like in Avalanche) were hard coded areas defined in the map with just a flag mdl to mark the centre.

It seems that this area technique using brushes is the only way its done in source, which may explain why the ladders dont port over.. tried changing all the ents to func_ladder but still nothing.

Excuse me posting in a mappers forum when I am clearly no mapper but I am always happy to test or provide our server(s)/clan members for betatesting

Note: I don't pass anything that I convert off as my own, it just started from a couple of the guys in my clan including myself who started off playing HL then Action Half Life and loved some of the maps from those and wondered how they would play in DoD, so my work (if you could even call it that) was running around going "status" in console and thinking "OK flag 1 here"

Dont wanna get flamed cos I'm sure I am the antichrist to some mappers but I just did it for some fun so now source is out I get sent maps from the clan guys saying "OOoo can we have this but in DOD:S and with flags please" and I'm an obliging kinda guy.
