Unlocking the transaction limits using plan - do add-ons cover total or only the tax year?

[KoiKoi]

Noob here, trying to get my head around transaction limits and plans. I know the free base plan generously works out capital gains and updates the dashboard for the first 10k transactions. If were to pay for a PRO for a particular tax year filing and add extra 1k transactions on the pro plan, would that cover for past and future tax years CGT calculations and dashboard updates (not filing)

Here’s a hypothetical

2021-2022 12k+ transactions, not exceeded CG threshold. No report.
2022-2023 12k+ transactions, probably unlikely too, got wrecked. No report.
2023-2024 Only 1k transaction, but expect to file a report.
2024-2025 1k transaction. I’m doing less on chain, and hodling more, will file a report
Total - 27k transactions

Can I just buy a PRO plan for 2023-2024 (10,000) add-on 10 x 1000 (+10,000) add along with the base plan of 10,000 cover all calculations?

Thanks!

Update: Trying different search terms, I came across this. I think this answered my question, but can team confirm, please?

Which plan to choose for multiple years, many transactions

Describe the problem: Hi - I have a large amount of transactions >20k, in each of three different UK tax years - do I need to buy a Pro plan for each year and add >10k additional transactions, or can I buy one Pro plan and add >50k transactions to that one plan? The options and explanations of what’s included aren’t particularly clear at the moment. Which exchange/wallet is this regarding? How did you import data into this wallet? What have you tried to fix this so far?

“if you only need reports for the latest year (but still need to maintain the other ~40k transactions in your records) then you can buy a Pro Plan for this year only and add 50k additional transactions to it.”
