question：How to copy the model from one LOD to another, and how do I create a new LOD?

[coocookie123]

I'm using version 0.48 of the tool, and when editing an existing WH3 model, I want to copy the model from Lod0 to Lod1, Lod2, and Lod3. However, in the tool, I only found the option to copy within the same layer, and it only allows copying within the current Lod, not across different Lods. I watched some tutorial videos and learned that there used to be a "Create LODs" function that could achieve this, but it seems like this button is no longer available in the current version. I'm a beginner with modding tools, and I would appreciate any help or advice.
