Sorting with multiple rows grouped
 

Is this possible? I found one other topic like this posted, but no
answer was given. Basically, I have a list of customer part numbers and
various dimensions and such thereof, and each part requires three rows
of entry - there's no way for me to get around having three rows for
each part. What I'd like to do is be able to sort (preferably by using
a command button or a combo box for different sorting options) these
part number entries, but all three rows for each entry would need to
stay together. Is it possible to group rows like this?
