Is there an easy way of changing accounting methods when I've already used FIFO in previous tax years. Where I live, I can now choose whatever accounting methods I want (LIFO, HIFO etc), and this year it will matter quite much. Can Cointracking in some way correct for earlier tax years to prevent counting coins twice? If so, how to do so? I also want it to be correct when viewing my "realized and unrealized gains".

Example 2013-2020 FIFO, switch to LIFO or HIFO in 2021, maybe switch back in 2022 etc.
