Search for associated items within 1 document

Is there a way to link multiple non-existant model numbers to a single document?

For example, our company has a lot of items that are similar so instead of having a drawing for each assembly or part when theres only 1 difference, we put reference dimensions on the drawings and have a chart on the drawing with all the actual items relating to that drawing:

Document is called 38xx.drw

     This contains 1 drawing with a chart to the following items:

3801

3802

3803

3809

Is there a way in Windchill that I can somehow attach the item numbes 3801-3809 (which don't have their own models or drawings) to the document 38xx so when I search for say 3801, the 38xx document will appear in the search.
