Hole table used in drawing, need to show other feature infomation

I am using Creo Parametric Release 4.0 and DatecodeM110

Information contained within a hole table on a drawing. Is there a way of showing the blind depth of a hole in a hole table, if so where can I find instructions? I had a quick try using parameters but I couldn't get it to work. I am also seeing standard holes labelled as M16x2 when in fact they have been specified as clearance holes, the only work around I have found is to create a normal hole at a specific diameter rather than using a standard hole generated using the iso.hol file.
