Portfolio baseline - dividends

After receiving my first dividend today I noticed that the dotted baseline in the portfolio overview moved up by the amount that I got as a dividend.
I would love to be able to customize the dotted baseline so that it only includes actual money i transferred from my bank account/credit card, and any money I made from dividends/price movement is reflected in the difference between baseline - solid blue line.
This should be a basic database call with one more filter and shouldn’t be too hard to implement i suppose?

Thanks a lot in advance!
