Hi all,

Was looking to tweak a few existing bionics settings (only json specific). Just wanted to confirm the only way is to edit the main bionics.json file?

“copy-from”: doesn’t work which is mentioned in the json\_inheritance.md. Also “override”: true, not possible?

Yep currently copy-from doesn’t work for bionics  
but this [https://github.com/CleverRaven/Cataclysm-DDA/pull/40155](https://github.com/CleverRaven/Cataclysm-DDA/pull/40155) might fix that
