Out of curiosity, how would people want this looking? I’d personally like this tagged per artist so each of these has a different icon, but would people prefer to have all these tagged together as just Bandcamp? Could they have different icons and names, but still be linked together to show all Bandcamp transactions in a list? I’d like to know how this functionality works on the backend, like how your database schema is set up to match merchants to data and how you group together when you tap “number of transactions” or similar.
EDIT: Additional thought: Have all of these labelled with just the artist name, and then include a #bandcamp tag in the notes, to make searching easier. Then you can see all transactions for the specific artist, and then all transactions with Bandcamp by tapping the tag. The other way round could also work, but I’m fond of having the artist as the primary merchant and Bandcamp as secondary.
