I figured it out. I pushed data to the other form using webparts data connection, then used the .(../preceding-sibling::(insert field name here)) command to make it replicated to all line items. Using SharePoint Designer 2010 allowed me to map all fields not just 1 by creating a data connection between two different webparts. I hope this helps anyone else who has the same issue.
Next task is to see if I can create a form that will pull all the information that's being gathered on one list and pre-populate a sharepoint doc library form I create so I can send it to vendors (embedded in an email) to fill out prices and hit submit to go to our SharePoint site.
The idea is to have all the same fields as on my form, but have a box at the top (drop down maybe) that says with rules if this box equals "field name here" then pre populate all the data in that row(rows) in the boxes below. I think an issue will arise when I try to do that into a repeating table but we shall see... Ill keep updating here unless no one cares lol.
