How to target Child Class element while keeping Parent Class selected?

Hello everyone!

I’m working on a project where I use Collections to display Portfolio Projects.

I want to give a custom styling to the even items but I can’t select the parent structure and after that to style some child from that element because the parent class doesn’t remain selected.

With Custom CSS I can do that with level selector:

*.project-item:nth-child(even) .second-featured-image { }*

but I was wondering if there is a way to do this from Designer Panel?

Many thanks!
