IH-01 Sub-Equipment above BOM List when viewing main equipment

Hello, I have an issue where I add sub-equimpments under a main equipment and then those sub-equipments showing up underneath the main equipments BOM list in S4/HANA. Ideally I would like them to populate on the top of the list when viewing in IH-01. BOM list is added in using IB02 and the sub-equipments are added in using IE02 under the Structure tab.
