IRR with dynamic measures

Pbix file: https://ufile.io/8lsvjz9t

Hi guys! Could you help me out with one Internal Rate of Return (IRR) question, please? The funcionality that I'm seeking is the following one: I have three assets on my financial data and, when I select their ticker, the box "IRR" should show the correspondent IRR value (in %) for the specific ticker selected. For the IRR function to work, I need to have Cash Flow values for the years to come. My problem comes mainly due to the facts that 1) each year of Future Cash Flow has a specific form of calculation (therefore I created mesures for each future year), and 2) certains elements involve webscraping updating, so both facts give me the problem that I have variables that are changeable and will continuously keep changing. Ideally, from my point of view, it could be solved if it would be possible to generate a table containing columns with 1) the different assets, 2) future dates (years) and 3) corresponding cash flows for each asset and year. Obs: inside the folder "_IRR", I left also an unsuccesful trial of doing the TIR calculations entirely on DAX ("IRR test", in case anyone knows how to solve it), but since it is quite difficult to isolate the IRR variable within the IRR conventional formula, Power BI wasn't able to understand the logic.
