If you have multiple Expenses and would need to split them all in the same way, the Copy Split Allocation could be helpful to save time with the Split.
First you will need to select the Split Expense that you already split from the original Expense.
Then, click on the Copy Split Allocation option under the Entry Tasks navigation menu.
This will copy the Split Allocation whether by % or amount, depending on what you’ve applied to the copied Split Expense. The Copy Split Allocation window will open with options of other Expenses where you would like to apply the same Split Allocation.
You can click individual Expenses form the list, or click on the Select All option to apply the allocation across all of the Expenses from the list.
Once done, you should see the new Split Expense(s in the Expenses section on your workspace.
