RGB Matrix Pattern "One by One" but alternate rows starts opposite end

[MattPillay]

Hi. I have (hopefully) searched correctly in this forum, for advice on how to achieve the desired effect mentioned in the Subject, but did not seem to get any hits on this pattern effect. It seems like a "normal" use case for this pattern, but I cannot seem to work out how to achieve that. Is there a preset for this effect.

I have my RGB matrix constructed in a zig-zag fashion, but want to have each LED (strip) switch on/off, following a sequence of a "snake". How can I achieve that?

Thanks for your assistance

And what if you arrange your matrix inside QLC+, in a zag-zig manner? Could mean some work but in the end, this will allow you to use all the matrix effects.
