Main thing is that QGis only allows you to use cartographic Coordinate Reference Systems. Most of the time archaeologist (I am one) we use totally arbitrary CRS. Once I posted a similar question and the answers were that if I could assign a coordinate in a mapping CRS that should do it (like an UTM for instance). Regarding on drawing systems for archaeology, I use acad, but it does lack the attribute table and its capabilities. My advice will be some how assign a mapping crs to your data.
