Creating offline posts WITH PHOTOS

I know this topic has been brought up before, but I am wondering when a version of the app will be developed to save drafts WITH photos while OFFLINE. I travel a ton and am away from wifi. I need to be able to create the posts offline and then upload them when I get internet. Why hasn’t this been done with this app? I have used other apps that have this capability and it seems like it should be easy to add this feature. Why not add it?? In the meantime, is there anyway to work around it or another app anyone recommends.
