In Fixed Asset Master data exist the Tab: Structure, where you can "link" the Main Fixed asset with it's components.

In reality this field does nothing, as there isn't any report to show the link between the Main asset and the components.

There should be a report showing this relationship between the two, and there should also be the option of having the Main Fixed asset as a no cost asset ( assignin no books, no values, no transaction), this asset should work only for reporting puprposes.

This is because there are no transaction on the main asset itself ,but the costs are only bared by the components. The main fixed asset should work like a totaling, the same as Total Main account work. Having only informational data and a report showing all the relation + parts.
