Use Cyfe's "Publisher" widget (located in the Social Media section) to do so.  

You can view your previously-published content, publish to multiple networks all at once (including the attachment of images) and schedule or edit content to be published in the future, whenever you want. 

Use the "Add Account" (select the first empty drop-down) to add multple business or client accounts for each social network! :) 

We recommend trying out a few test posts before scheduling your content in bulk -- we think you'll love Cyfe's social media Publisher widget!
