This gives me a single number format, but I want to stay depending on how many files I list. For example in an album where there are 10 files, I want the first to be 1/10 and the last 10/10

Something [like this](https://community.mp3tag.de/t/regular-expressions/521/5?u=zontir), but in an inverted way.

How can I accomplish this?
