Reference script of arguments that can be linked in other scripts

Hi all

I have multiple scripts that perform a function depending on the track name. eg colour the track depending on the track name. They all use the same Switch function set.

ie

    switch (true) {
        // lead vocal
        case (trackName.includes('lv')) || (trackName.includes('lead')) && (trackName.includes('vocal')) || (trackName.includes('vox')):
            functionToPerform(8, "Section 2", 2);
            break
        // backing vocal
        case ((trackName.includes('harm') || trackName.includes('group') || trackName.includes('chant') || trackName.includes('gang') || trackName.includes('bv')) || (trackName.includes('back') && (trackName.includes('vocal') || trackName.includes('vox')))):
            functionToPerform(8, "Section 2", 3);
            pickColour(22, 2);
            break

Problem is, if i want to add or amend one of the arguments, I have to do it to every single script.

Would it be possible for the Switch set to sit somewhere, and have each script refer to that single Switch set that i can update as I go?

Template is not ideal as I'd have to change my whole folder structure... but if that's the only way, I'd appreciate some help with how to accomplish this.

Thanks all

Best
