I'd like to know if it's possible for the filter bar to show only the results where an albums' catalog number is present in the %ALBUM% field?
For example, I have music in my collection where the catalog number appears like this...
Album: My First Album (CATNUM001)
I know a simple check for a open parenthesis in the filter bar willl return the results but there is a lot of false positives, e.g. Album: Another Album (The Remixes)
In the case of the catalog numbers being in the album field they are always uppercase and a mix of uppercase letters and numbers, no symbols)
Any help is much appreciated!
