Brilliant ideas for SmartFlow

I'd like to know if there is any way we can see the total time that a patient has been in the hospital since admission into SFS. This would be a good option to add into patient parameters.

Instead of seeing X:XX time for "admission" ; then X:XX time for "Tech exam" ; then X:XX time for "Dr. Exam" etc... , It would be nice if the total time was displayed somewhere that can note how long the pet has been in the hospital from the moment the pet was transferred into smartflow.
