Add multiple members to Office 365 groups

Hi Guys,

Currently I am able to add member to the Office 365 groups using the following Graph API.

POST https://graph.microsoft.com/v1.0/groups/{id}/members/$ref
Content-type: application/json
Content-length: 30

{
  "@odata.id": "https://graph.microsoft.com/v1.0/directoryObjects/{id}"
}

But I am able to add only one user per request. Is there any way to add multiple members in a single call?
