Hello! I'm looking for a way to copy a set of rollable tables from one system to another. Specifically, I'd like to grab a bunch of the oracles from the "Ironsworn & Starforged" system over to a GURPS game I'm running; to help with generating content on the fly.

The rollable tables I'm looking at are pretty basic, but extensive - the ones I'm after are mostly roll a d100 for a textual result. I'm able to go through and individually import the table (from a compendium), export it to my file system, switch game systems, and import it there without issue; but I'm looking at a few dozen or more tables that I want to do this with! I'm hoping there's an easier way. They're all nicely bundled in a compendium; but I suspect that's part of the issue - is there a way to move a compendium from one system to another? Or another way to move rollable tables en masse?
