I wrote a guide (like @Gorro_Rojo said) for this some days ago. Check it out.
As @Gorro_Rojo said and is written in the last Sprint review (53) Collections will make it easier.
Collections
It’s Sets with a twist: you can choose what’s inand what’s out
. Manually reorder with drag-'n-drop, remove multiple Objects from your Collection, or completely delete them from your account, it’s all up to
you!
