Kits
Parent assets and the members that belong to them.
A kit is an asset that has members (child assets) and may itself have a parent.
Example: a laptop kit (parent) with the MacBook, charger, and sleeve (members). You can still check out the parent or a member, depending on how you work.
On the asset screen, parent and members show as related tags.
Use a clear tag scheme (for example LAP-014 and LAP-014-PSU) so scan and audits stay obvious.
