Sorting scripts by axis?

Hi all, I recently upgraded from an OSR2 to an SR6. I’m wondering if there is any software that can help me sort through my old multiaxis scripts to pick out the ones that have the extra axis?

A lot of my script collection uses the combined .funscript file. Being able to easily find the ones that use the L1 and L2 script would be great.

Thanks for any help in advance.
