Hello
Yes you can create new Views in Site Admin. And define View network. For example put your Service View behind Design or behind Manufacturing view (have to decide if your Service BOM is more inherit from Manuf or design levels ... )
Do you have MPMLink ?
cause out of the box , you can change Views and manage xBOMs with PDMlink.
But with MPMlink , some equivalence links are created between Views. And some attributes and Vizualization can be propagated ....
So you should be able to re organisze your service BOM with few sub components. But correctly vizualize the full Product
