Does gta online support user generated missions?

Grand Theft Auto Online is the online multiplayer component of Grand Theft Auto V, developed by Rockstar North and published by Rockstar Games. The game allows up to thirty players to roam the fictional state of San Andreas, which includes the city of Los Santos and surrounding countryside. While the open‑world design gives players freedom to explore and participate in cooperative or competitive modes, the official Wikipedia entry for the game contains no mention of any system for creating or uploading user‑generated missions. Consequently, based on the verified source provided, the game does not include a feature that would allow players to design or publish custom missions for others to play.
