Model File Editing

Hi, I have already addressed this problem or editing models and Klemen has also already explained where to find the folders and so. But I would find it good if there is a possibility to add changes to models via file changes. Meaning that you don't have to reassign all the blocks that use the model to the new model and you don't have to use a different model with a different name. So that you have a model and that if you have made a change e.g. in Blockbench and have it as a .json file, that you can simply replace the already existing model with the new one.
