Scale all things inside UI canvas

I'm making a basic inventory system for my survival Unity game. I recently learned how to setup a Canvas Scaler to scale the contents of the panel, but things like the items and the slots inside don't scale properly, leaving me with slots that are small but spread out FAR too much. I would rather the slots get larger and stay proportionally the same distance from each other. Is there any way to scale up all the children of the canvas and the children of them and so on? My hierarchy is Canvas > Main Panel > Small panels (like hotbar and main inventory > Slots (Images) > Items (Images). Thanks in advance for any help you can provide.
