Can i pull more then 30 days of wallet journal?

Is it possible to see 60 days back in time in the wallet journal?

There must be more people with me who settle accounts from the first to the 1st of each month. And several people like me who cannot always do this exactly on the day.

Therefore, I am looking for an extended time frame 60days. So that we can settle accounts from the 1.9.2023 to the 1.10.2023 on the 13.10.2023

No. You have to pull the data and aggregate/store it yourself for longer time spans.
