Group editing of Scheduled posts

After scheduling a post on multiple account, I'd like to make an edit in one scheduled post, and clicked "Appy edit in series". For example: let's say I created a post in 3 accounts. Later I want to add a photo. I'd like to add it and choose the change to affect all 3 posts (actually 1 post in 3 channels). I hope this is clearly written :) Thanks!
