any way to make separate portfolios / accounts in etrade or robinhood?

is it possible to group stocks in different groups so you can see the total return for just specific stocks together on etrade or robinhood? for ex, some stocks bought in june 2020 in group 1, stocks bought in may 2020 in group 2. i want to see the total return for group 1 only, not the total return off all my stock
