Import FBX into level with convex hull

Hello there, new to Unreal in light of recent events.
Is it possible to somehow automatically generate collision mesh on all imported geometry when importing fbx? I can see that it generates some simple geometry, but it has huge offsets. What works for me is convex hull generation, but I can only do that per each geometry in fbx individually. My fbx consists of 140 models inside and going through each on individually is a huge pain. Is it possible to somehow automate it? using c++ api maybe?

tried chat gpt for some help and it suggested python script, but it doesn’t work. method DataprepSetConvexDecompositionCollisionOperation in unreal package doesn’t exist.

import unreal
import os

operation = unreal.DataprepSetConvexDecompositionCollisionOperation()
operation.set_thresholds(unreal.DataprepSetConvexDecompositionCollisionThresholds(0.1, 1000, 100000))


recipe = unreal.DataprepRecipe()

recipe.add_operation(operation)


folder_path = "D:\Projects\MedievalMadness4\Content\Art\Trees\Tree_01\Meshes" 


static_meshes = get_static_meshes_in_folder(folder_path)

for static_mesh in static_meshes:
    result = unreal.DataprepLibUtils.apply_recipe_to_static_mesh(recipe, static_mesh)



def get_static_meshes_in_folder(folder_path):
    static_meshes = []

    files = os.listdir(folder_path)

    for file in files:
        full_path = os.path.join(folder_path, file)

        if unreal.EditorAssetLibrary.does_asset_exist(full_path) and \
            unreal.EditorAssetLibrary.does_asset_support_editor_view(full_path):
            asset_data = unreal.EditorAssetLibrary.find_asset_data(full_path)
            if asset_data.is_valid() and asset_data.asset_class == unreal.StaticMesh.static_class():
                static_meshes.append(asset_data.asset_name)

    return static_meshes
