Would it be easy to add beta weighting portfolio greeks as feature, perhaps to the portfolio window or the account positions window? The formula isn't proprietary, I think, as there are plenty of articles on the web discussing the concept.
When we have many positions, one surprisingly effective way to consider portfolio exposure is by beta-weighting each greek of each position to some index, like SPX (user-configurable), then aggregating them (sum, or product, or something else, I'm not sure on the math).
I'm not that good of a writer, I thought I'd include this excerpt and link explaining the concept in a different way. Hopefully, it's regarded as still on topic.
"Beta weighting is a means for investors to put all of their positions into one standard unit. It is a way to look at an entire portfolio and understand how it will change with a move in the market. It tells us about the size, diversity and general risk of our positions." --from https://www.tastytrade.com/tt/learn/beta-weight
