In my individual list I have a column listed as Death Date and another as Death Place. It is easy then to go through the list and check missing death dates. Instead of an actual date or a guess I just write deceased. it is just a matter of right click-edit-write "deceased"-save. Then when you reach the next missing entry you just hade to write a "D" and the program writes the rest of the word for you.
Of course you have to format the template first to show this on the individual list.
I hope I have explained this clearly. I realize that you were looking for a program to do this.
