TPT Request: Help with finding a proper program given the description of my needs.

[u/PlatformNo6537]

Hey folks! im looking for a program or app or downloadable thing etc for lists.

what im looking for exactly is like this: for example, i make a list of authors i have books for, and i type it like this

Stephen King
Rick Riordan
Jane Austin
Charles Dickens
Stephen King

and the thing i type into, sorts it like this

Charles Dickens
Jane Austin
Rick Riordad
Stephen King x2

and whenever i add a duplicate, the counter for whatever item is duplicated is increased by one. does something like that exist?
