We were given a cordless lift with nothing to hold onto to lift them up or down, only the bottom slat. Can a pull string be added?

Hi: Thank you for your question. This particular product does not offer handles for the bottom rail as the bottom rail is what is used to push up and pull down to operate the blind. There would not be an area to attach a pull cord. You are welcome to reach out to Lowe's to discuss your options if you prefer a corded lift blind.
