What is the best practice for features that we expect run over 1 or more sprints?

[Jennifer Saunders]

I am trying to work out the best practices for planning epics. I have split the epic down into sizeable chucks of feature and stories that will be tested at the same time. However the features are likely run over 1  or more sprint. And i would prefer to plan stories into sprints. My first thought was to add the features (Hierarchy level 0) and add the stories as subtasks (Hierarchy level -1). However the issue with this is you can only all subtasks under a feature to the sprint not individual ones. Another thought is to add a label to the stories that fall under a feature, but this will make planning more difficult. Is there another more effective way to do this? 

Many thanks,

Jen
