Bulk Editing

Summary: Let me select multiple cards and apply one edit to all of them — custom price, parallel, condition, tags, or quantity.

Problem: Every edit is one card at a time. I recently ran market comps on my collection and needed to correct 33 stale prices; that meant opening 33 cards individually and repeating the same steps. I also own multiple copies of the same card (my collection has 62 duplicate groups across 152 entries), and each copy has to be edited separately even though the change is identical.

Proposed behavior:

• Multi-select from the collection list (tap-and-hold or checkbox mode; shift-click on web)

• Apply to selection: set custom price, set parallel/variant, set condition, add tag, move to binder

• Bonus: a quantity field on a single card entry, so 5 copies of the same base card can be one row instead of five

Why it matters: Serious collectors maintain hundreds of cards. Without bulk actions, keeping prices and attributes accurate doesn't scale past ~50 cards, so collections silently go stale — which undermines confidence in the app's valuations.
