HDL Import - Is it possible to validate DefaultExpenseAccount given in Worker.dat

Summary:

When sending a MERGE using Worker.dat for an existing employee, if we send invalid combination for DefaultExpenseAccount, HDL load doesnot show any error and existing ExpenseAccount data get erased for the employee. Is this the expected behaviour?

Is there any out of the box functionality or any work around to impose validation prior to merging the data
