AutoCAD Inventor :: Multi Sheet IDWs And Work Flow

we have simple assemblies with bolted weldments and few misc. parts. most assemblies are 3-20 parts a typical project would have:

-a few laser cut parts, some plastic and hardware. these items need to have part drawings sent to a vendor. 

-some in house cretaed parts that need a drawing

-assembly drawing for our shop

i think i am seeing that by having one single  IDW its getting hard to send all the drawings to the people that need them. an example would be if a vendor calls about one part, i may send him a 4 page PDF and tell him to look on sheet 2.the other issue that i have is that my standard work flow is:

-design a product

-hand of to another dept for them to enter SKU numbers for parts and assemblies.

so my file names never match what the final product name is. i have been using fields in the iPROP, but it would be nice to revise file names when SKUs are created. im guessing vault would be the tool for something like that?
