Adding a Subvendor to an Expense
To add a subvendor to an expense, make sure you add your main transaction as a disbursement and then when you add your subvendor transactions you will select the subtype of "Memo" and save it. Click modify and then click the button that says, "Additional Details." In that screen you will see an area to "Add Transaction Links." In this area you want to search for the main transaction and link it.
