How I can reduce the overall actors by a certain percentage?

I bought castle assets from the Asset Store.

This asset is composed of several static meshes.

So to reduce the castle, I have to reduce the mesh one by one.

I want to reduce the overall actors by a certain percentage at once.

How I can reduce the overall actors by a certain percentage?

Thank you.
