Is there a way to sum multiple Salesforce opportunities in Trello cards?

[Darren Colclough]

I have a board that captures new ideas submitted by our team. The submissions include opportunities in Salesforce (using the Salesforce power-up). Often, there is more than one opportunity per card.

Out-of-the-box, I get:

1. The correct sum of all linked opportunities on the front of the card
2. All linked opportunities listed in the body of the opened card
3. The highest opportunity value on the front of the card along with its close date

What I'd like is to get is:

1. The correct sum of all linked opportunities on the front of the card (we have this)
2. All linked opportunities listed in the body of the opened card (we have this)
3. A sum of all linked opportunities on the front of the card
4. A sum of all linked opportunities in the body of the card

Is there a setting or modification to the Salesforce power-up to make this happen? Is there another power-up that picks up from the out-the-box-functionality to achieve our desired outcome?
