Allow core entity copies not to have the "copy" in the name/slug/etc

Is your feature request related to a problem? Please describe.
We use entity copy to copy entities to other channels. We do this by assigning an entity to a channel, copying it, then removing the original entity from the channel. It's kind of a template based approach. The ony thing that would make our life a little easier is not have the (copy) and -copy added to names and slugs. It would be a good default argument option to be able to disable.

I do understand that adding (copy) is the obvious thing to do. But not if you're using an entity as a template

Describe the solution you'd like
The option to disable names and slugs, etc to not be changed through a copy operation

Describe alternatives you've considered
We do post processing now. But it can be a bit of a pain with facets across products and variants.
