How do you get Expense to Sync Merchants from Zoho Books?

If we are creating expenses in zoho expenses and then syncing them to zoho books, how do we sync the merchants list?

I see that in the expenses app, the customers list is syncd to books no problem.
what about the merchants list (vendors?)

Do we just manually create them in expenses and name them the same ?
