Take a look at this video, which I have fast forwarded to the demo of the Analytic Simulation:
It was introduced in Odoo 16 and allows you to add Analytic Lines linked to a GL account that represent amounts that might be added.
This means you can add your expected profits and losses in Q4 and see a "simulated" report for the entire year based on the assumption that the manually created entries accurately represent the entries that would be created in Q4.
It's basically allowing you to time travel to several possible futures.
BUT only if you guess correctly
Create lines for an account called "best case" and others for an account called "worst case" then run your financials and see what your future could look like!
