How do I select & copy multiple layers?

How can we select multiple layers in 2025? You used to be able to hold shift & click another layer, but this no longer works.
Basically, I’m trying to copy 22 layers from my page: https://www.nomansskyresources.com/bone-parts onto the subpages https://www.nomansskyresources.com/bone-parts/{title} from the layer titled ‘Predator Title’ all the way down to the bottom ‘Horned’.
This isn’t the only time I’ve needed to do this with dynamic (all) pages & (title) pages.
Obviously, having to copy individual layers, change to the other page & paste it, then go back & copy the next layer, etc. is very time consuming & needlessly difficult.
There must be some easy way to select a lot of different layers at once in order to copy them.
