使用VS2005和VSS有没有办法为签到添加注释？

All the googling around hasn't found an answer for me yet... I have one of our devs that is using VSS and VS2005. Checking in works (abeit quite painfully across the 'Net) but there doesn't seem to be a way to put comments into a checkin (unless you embed it in the source file maybe?) I'll be one of the firs to admit that my knowledge of VSS is pretty slim, and if there's a "Duh" answer, would be happy to hear it :)All the googling around hasn't found an answer
