We have accessories that need to be accepted, not just assets, but it's very difficult to see which are outstanding.

Describe the solution you'd like
Change the Unaccepted Asset report into Unaccepted Items, and allow filtering just to include assets, accessories, etc., or combinations of them. This would be easiest for users with a tickbox list to show , defaulting to all ticked, but could be a dropdown with All, Assets, Accesories, etc.

This would also have an impact on the user's unaccepted assets screen, which could show the same filters to be generalised to Unaccepted Items. (See #5265.)
