Edit a keynote in group

I?m making a Keynote project with two friends, but it?s kind of annoying to have many version of the same project every time the file is edited.
Is there a way to edit it online? So we can see changes others are doing. Like with icloud sync but on different accounts

I don't like the web version of keynote
