To share or schedule your feed content manually, you need to first turn off the automatic sharing. See here to learn how.  

1. After you have turned the Feed button to 'Inactive', click on 'Content & Feed' from the side >  Feed Content, from the sidebar menu. 

2. Select 'Schedule Feed Content' where all your feed content will be displayed. 

3. You can select which Feed content posts you want to view from the 'Viewing All Feed' drop-down menu. 

4. Now you can individually select the feed posts you want to schedule and share. Select from the various Group(s) and Account(s) you want to assign the posts to.

5. Click on 'Add to Queue' or other scheduling options from the drop-down to schedule your Feed content manually. 

Scheduling your RSS Feed content manually gives you the freedom to re-schedule your posts at any time.
