Hi zledsrrato,
your post unfortuntely is the latest entry regarding the feature which the developer referred to as "Ability to re-edit text, or "text layers", or some variation thereof" in the respective post "Popular Feature Requests" (which has been updated in 2018-02).
I still have high hopes regarding the implementation for 4.5 or "post 4.5", so I suppose this will be a little better then ?.
