Zoho Expense - add or change merchant after bulk add expenses?

When adding expenses via "bulk add expenses", there is no line item to add the merchant name.  After the bulk add, going back to each individual expense, there is nowhere to add the merchant name.  It seems the only way to ensure there is a merchant name is by adding expenses one by one.

Is my understanding correct?
