Can I create a view based on a specific state transition date?

I have been struggling with this one for a while. Till now I have found some workarounds, but now I cannot come with anything. 

  • If the workflow has a signature, can I use somehow the signature reason and date for it? 
  • If the workflow does not have a signature, how to do it? 

In both situations I cannot used the "moved into current state" neither "last modified". 

Thanks,
