Is your feature request related to a problem? Please describe. 🤔
It's simply not practical to add trades for every single log type, especially on a modded server with close to a hundred log types.

Describe the solution you'd like 💭
Allow specifying a tag rather than item (either through "#minecraft:my_tag" or some kind of "type": "tag" entry)

Describe alternatives you've considered 🔄
As mentioined before, adding every single trade is just not doable.
