Request: findAboveAllColumns()

[SoorajKumar]

Hi,
First, thank you so much for such a wonderful tool!
When importing CAS pdfs, I sometimes see the mutual fund name in column B instead of A:

To address this issue, I would like another function in the src/lib/template_helpers.ts file called findAboveAllColumns() or similar, which could combine the strings from all columns first, then run a regular expression check. This looks like a 2 minute job using AI, but I'm having a hard time building from source, so I'm requesting this function to be included in the main repository.
