Prepaid Assets

We are using Asset Management to track prepaid assets coming from AP/PO and wanted to know if any users have any experience with this capability/how are prepaids normally handled in AM? Is there a way we can specify a specific start and end date for the asset? Are you using existing accounting templates or did you create new ones/Is there a way to manipulate accounting templates for prepaid assets? We already created specific profiles and categories for these prepaids.

Any ideas would be helpful! Thank you
