Each user now has the maxuploadsize field in their user record, which designates the largest single file size that a user can upload. This setting can be viewed in the user's profile in the WebUI and is set as an Enterprise level setting.

Just as the user's spaceamount (their quota) can be set via the Box CLI, using the --disk-space switch when updating a user's record, there is a need to be able to access a switch to set maxupload_size when updating individual user records via the Box CLI.
