File names

Why does the program not show dep names in the file names when saved. It only shows both spouses name but
I have a single parent with 2 dependants and it only saves as the one parent in the filename even though all coupled.

It is hard to remember when looking at the file names in the directory if you did the other 2 dependants or if were looking for them rather having to open up the return to see if there . I cannot tell if the family as a whole is there in the directory
or not.
