Managing Multiple Checklists

Hi, 

We use multiple Checklists based on the Product Type being run on our equipment. The issue is our Mechanics have to select the appropriate checklist for the Product Type and still Process the other Checklists, since we "require answers to all questions before closing checklists".

 Is there a better way to Select the appropriate Checklist from the "scheduled documents" or "occurrence specific documents" lists which then deselects or make the other Checklist not applicable.

Or can a drop-down selection within a Checklist selects a portion of the checklist and makes or checks the other sections "NA"

Regards

Brian
