Financial Reporting Web Studio - Display previous period without adjustment periods

Hi !

For my custom FRS report, I would like to create a report where I display selected period in one column (let's say 22-01) and previous period balance in another column, without taking into account the adjustment periods we defined (If user selects 22-01, then I would like in my second column to see balances for 21-12, but not balances for 21-12-ADJ1 or 21-12-ADJ2 for ex).

Is that achievable with a specific formula or setup in Financial Reporting Studio?

Thanks !
