Drag and drop multiple items in a backlog?

Is it not possible to drag and drop multiple items to re-order them in a list view?

I’ve been evaluating Fibery and it seems awesome, and was planning a go-live for my team on Monday. But when rehearsing a data migration yesterday, I discovered that apparently it’s impossible to re-prioritize a backlog by dragging and dropping multiple items. This seems like such a basic feature - am I just doing it wrong?

I figured out that I can multi-select with Option-Click and Shift-Click (but Shift-Click doesn’t work reliably). But then once I have multiple items selected, if I drag them to somewhere new in the ordering, only one item changes rank.

Brave on macOS, if that matters.

If this doesn’t work, how does anybody manage backlog ordering? One card at a time?

(Semi-related: it looks like bulk editing across more than 2 databases doesn’t work? I added an “Overhead” database in addition to the Sprint and Story databases, and now apparently that means I can’t bulk-edit the Priority field, either!)
