More bulk tools for production assemblies

At any one time we have 100s of assemblies on Dear and they are often authorised but are waiting for products to arrive before they can be changed to Work in Progress.  When a purchase arrives we have to open each one in order to check to see if it is possible to take it to the next change which can take hours.  Please can you implement a change to make it possible to easily find assembles that are ready to change to Work in Progress.
