Is it possible to have 1 sub that is portioned between 2 subs? EX: Sub A (Parent), Sub B, Sub C Sub B rolls up to Sub A Sub C is new 1% of Sub C should be in Sub B, 99% in Sub A. So when they run an unconsolidated financials for Sub B, 1% of of Sub C should be in there Hopefully I am explaining this clearly, is that something NS supports?

Unfortunately NetSuite doesn't support partial ownership of subsidiaries. I've seen some documentation that attempts workarounds, but I've not seen anything really work well. You generally would need a 3rd party tool to deal with that.
