Canny allows for bulk actions across multiple posts at once.

Manage multiple posts at once using the ⌘ Command / Ctrl and ⬆ Shift keys in the feedback tab:

For users participating in the Canny Ideas beta, this will be the view:

To select multiple posts one-by-one: Hold the Command (⌘ on Mac) / Control (Ctrl on Windows) key, then click the posts you want to edit (including the initial post).

To select a block of posts at once: Click the first post, then hold the ⬆ Shift key and click the last post. All posts in between are included in the selection.

You'll then see the bulk edit options!
