Recognizing an Item on a Supporter in the Location

So I want to test if an item is in the current locations. Generally, this works with a snippet of code like:

if scissors are in the locations: do something;

However, if the scissors are on a supporter or in a container, this doesn’t work–even if said supporter or container is in the current location. Is there a more general phrase that I could use that looks on supporters and inside containers?

if the location encloses scissors

Thanks for the prompt reply! Works like a charm.
