How to Reinvest via Deposit

I have a pie with a handful of Vanguard, iShares indexes. They pay dividends into the pie, which obviously sit under Dividend Income in ‘Total Gained’.

How can I use this when I tap ‘Invest’ and invest money into the pie?

I can obviously use ‘+ pie’s cash’. But this is cash, not the dividends sitting in ‘Total Gained’.

Thanks for any help!

Total Gained is just a tot of all dividends paid into the pie. If you’ve been reinvesting dividends before it won’t subtract from Total Gained. Think of it as a running total of pie income, not income that is yet to be reinvested.
