Importing Quotes with Line items already

Hello,

I am trying to import our system quotes and we have line items already attached to the quotes. When I import the quotes there is not a field for line items. How would I do a mass import of quotes with line items already assigned to them. Any help would be greatly appreciated.

When you “Import Quotes” you separately “Import Line Items”

1 - Import quotes (no line items)
2 - Import Line items (reference Quote number)
