Can I have a total in a list, using customised fields?

[Jocelyn Cole]

I've added a value to each card using the custom field power up, but I'd like to have total for all the cards in that list? Is this possible, either using this power-up or any other?

@Jocelyn Cole you can try the free Card Size Power-Up. It allows setting weights for cards, and seeing the totals per list, assignee, or label

@Jocelyn Cole this is something you could do with the API. I don't think it would be possible with Butler (and they're not currently accepting new accounts anyway) but here's the code that would do this in Trellinator:
