project or sub-project content type?

Hi...

I'm new to openscholar, so please excuse my question if it's naive.

I'm interested in using the "project" mode of OS for research group web sites. Most of the necessary content types are already there, but I think we will also need a "project" type -- research groups have several projects. (I guess maybe a better term would be sub-project, since the top-level is termed a project).

I thought about using one of the other content types and changing the name in the menu, but none fits quite right.

Before I consider trying to create this kind of content type, I wondered if I've missed something or if someone has found a simple way to deal with this.

Thanks--
