Adding a User to Simple AD Directory in Workspaces - AWS CLI

I have recently created a Simple AD directory for the purpose of launching a bunch of Workspaces. Normally, I create the workspace through the console when a user requests one. First, I add the user to the Simple AD through the workspace management console, then I launch the workspace for that user. Now, I am looking for a way to add the user and create the workspace though the CLI. However, it seems that AWS only allows Simple AD user addition through the console. The only alternative I found was to add the user through WorkDocs, but this way, I have to set the user's password (required parameter) rather than having the user set their own password. Additionally, my intention is to create a workspace, not a WorkDocs site. I don't understand why would AWS let you programmatically add the user to Simple AD through WorkDocs, but not through Workspaces. Any feedback is greatly appreciated.
