Pcgi in dwmx?

Well, here is the thing. I have a website on which I’ve had problems with the host before when trying to upload files. I have had to resort to using .pcgi instead of php as this is what they use or something. I know little about it all, I jsut know it works. Most times. It’s not working now, and I actually think it’s something to do with the host…
but I suppose my real question is, how can I get Dreamweaver MX to recognize this ext, pcgi? it doesn’t and I want it to… can I fix this so I don’t have to rename the ext every time I change it?
thanks guys…

maybe you should just rename the file to .cgi then when your done rename it back.

I already do that, that’s not the question.
