Allow dividends in assets instead of currency (e.g. staking)

at the moment:
Dividend feature only allows to track dividends in Fiat (Eur/Dollar)
Dividend can also tracked in asset (e.g. Bitcoin)

reason: Staking is a business concept, in which you get e.g. monthly rewards for your invested asset directly in then bitcoin. e.g. 0.002 bitcoin which you need to add to portfolio.

Current workarroung: I need to buy the amount of bitcoin and then in a second step balance this with a dividend in fiat to track my growth correctly.
