Ability to use "filename_encoding = base32768" with "suffix = .mp4/.jpg, etc"

base on Custom encrypted suffix · Issue #6932 · rclone/rclone · GitHub and crypt: adding an option to set a custom_suffix #6392 by jladbrook · Pull Request #6958 · rclone/rclone · GitHub i had the impression that on v1.63 it was possible to use this flags for a desired outcome of "encrytefilename/data.mp4, jpg, etc" if this is not the case am wondering how much work would be needed to make this possible? thank you in advance.
