The Features List view allows you to bulk edit features and attach them to Initiatives. You simply filter to narrow down your list and/or check the features you want to edit. You can read more about bulk editing in our support document, Copy, move or bulk edit features.
Thanks you very much!

We usually create the initiative then create a list of features in the board view. Would be great to be able to select the initiative for each feature in a table view/bulk mode instead of having to open each feature to be able to select an initiative.
