Populate negative & positive amount on semi manual reconciliation instead of absolute value

I am trying to find config which can populate negative or positive amount for trans_amount field.

currently, it shows absolute value for all transactions. BANK_STMT_TBL table have obsolute values for all transaction type

Where I can config to generate negative & positive amount?

FYI

I checked Bank Statement Codes (Banking> Administer Bank Statements> Bank Statement Codes) where every "summary type" statement code has CR/DB flag assigned

& also trans code(like check(-)or deposits(+)), payment method are assigned for few statement code
