How would I manually compensate +1 stop on my light meter using the ISO setting?

I am new to film photography and just wanted to double check something I am confused about.

So imagine I am using a fully manual film camera with an older light meter in the cold shoe. No exposure compensation feature so I need to do this manually. I attach a yellow filter over the lens, which I need to compensate +1 stop for.

So if my film ISO is 100, before metering and taking pictures with my camera, shouldn’t I dial in 50 ISO on my light meter to compensate for that +1?

That way I don’t have to meter and remember to constantly change the aperture or shutter speed by +1?

Thanks.
