Hisotry of payouts

Is there a good way to get a history of payouts for a darknode. The 2021 tax season has come and nearly gone and I tried to track what I can but it has been awefully annoying to manually check this every month. By my thinking, if I claimed my rewards everymonth which I did, I should be able to see all the transactions on the Ethereum network but that only works until roughly last summer when we went multichain and no longer had to claim rewards manually. It would be great if I knew of some way to just check the REN blockchain and see what the payouts were since we went multichain.

Does anyone have any advice on what I can do to start consolidating information?

Thank you good sir or madam
