Asset History possibilites?

Asset History possibilites?

For the most part, Assets do not change. However, we do schedule a scan every day. When I go to the Asset History, I see pages and pages on "No Changes". I don't care about these items.. I only care if an asset changes.
 
1) Is there a way to only display in Asset History when the asset actually changes? This would save me a bunch of tie trying to pick out the "Changed" from "No changes" in the huge list returned.
 
2) Is there a way to search asset history?
      example: I want to know what assets were ever assigned to a specific user and when? I want to know what userid was last logged on to which assets and when.
 
These two items would help me, and I'm going to assume many other folks tremendously.
