Hi Christine. I apologize for the long delay answering this question of yours. I’m not sure how it slipped through the cracks, but hopefully I can still help you here.
Yes, with Event Aggregator (EA), you enter each Facebook feed individually.
However, you could activate Facebook Importer plugin, bulk-enter your Facebook feeds into it, then use EA’s migration from FB Importer to EA.
You could request this as a new EA feature (or maybe search to see if the idea was already posted by someone else) at our plugins’ UserVoice page.
This allows others who are interested in that feature to easily voice their support. We frequently review suggestions there to find out which ones are popular, then we implement as many of them as we can.
If you post it / find it, feel free to link to it from here in case anyone comes across this forum thread in the future.
Again, sorry for the delayed reply, and let me know if I can be of any further assistance with this issue.
Thanks!
