Please can you set a particular balance sheet report for a year rather than computing previous years in addition like from 1/1/21 to 31/12/2021
Balance sheet is prepared for a particular date not for a period.

It does not make sense as the only starting date is the company starting date as BS items are perpetual. If you want to know the difference between two periods you have to generate 2 BS reports each with the different end date as the start date is that of the company for each.
