How to Convert Curves to Grease Pencil in Blender 3?

Question

Using the Import-Export SVG addon, I imported an SVG as curves so I can make a 2D animation with it. Only problem is, curve layers don't evaluate in 2D-style top-down layer stack, so all the layers show through each other. I need a way to convert them to grease pencils so the layers stay behind or in front of each other depending on index position. This looked promising, but the solution is a script which no longer functions in Blender 3.

Note: Import > SVG as Grease Pencil only seems to work for really simple SVG files.

Turns out you can convert multiple objects by selecting all of them with Ctrl+LMB and then clicking any object with RMB > Convert To > Grease Pencil.
