Yes, there is a way - it is a "hack" of sorts.

In the dates, select 2019 as if you want to look at a profit/loss from 2019.  When you do this, it opens up custom date comparison options in the "Compare another period" option below.  Under previous period, check the custom period and enter your 2019 dates that you want to compare to.  Then go back to your original dates and the custom option stays.  You will have to play with it until you get the hang of getting your options to stick but it's a great option to compare against 2019 since 2020 was #%#$^#$%#$
