Can you measure between 2 parts in an assembly drawing?

I have two parts in a drawing the material and the part.
I want to dimension the hole depth for the prepping op as it is close to the part
so the operators can see the dimension, but also visually see how critical the
hole depth is, but I cannot select the hole,
I have tried all the filters but no joy.

I possible to do it like this ?

I’m using SolidWorks
2017

Can someone please help?

Thanks
