Copy a recipient list from Outlook 2011 into an Outlook Web Access (OWA) Group

Contacts in Outlook Web Access used to give you the option of dragging recipients from a folder containing contacts synchronized from Outlook 2011 to the Exchange (Office 365) server. This worked in Sarfari and other browsers. Now there appears to be no way to create a contact in OWA (Office 365) in browsers other than Microsoft Internet Explorer except to type or paste a name or part of a name and either add the address manually, or find an individual match for one name in the cloud address list. Is there any way to add multiple recipients to groups in OWA for Office 365 if you aren't using Microsoft Internet Explorer to display OWA?
