exposing ElastoplasticMaterial values?

[StudioTatsu]

Can you expose the current progression values from the ElastoplasticMaterial?
It would be great if we can get the comparison variables from plasticRecovery and maxDeformation equations.

Basically, the variables used to compare the current recovery value to plasticRecovery amount and current deformation value to maxDeformation amount. 
If those values are already exposed, what class do they reside in?
Thanks
