Import as layers

🍪 Migrated from LPINK-853191 - Import multiple single layered SVGs as separate layers. Split from #2334 (comment 323651208)

Mentioned Use case:
To convert svg files to ilda file (click me) for laser light shows.

OP (Harry Joos) said

I only can use inkscape svg files to convert later on to ilda files used for laser presentations. To generate a laser animation, I need about 2000 layers in my svg file.
For now, I do this manually by importing layer by layer. Is there any option, plugin or whatever to automate this process? Like you have the import in photoshop/GIMP where you can convert multiple files to different layers. This would be a Great help for me. Thanks.
