Override property set value in proxy level

[dpatty]

Hi , 

We are in apigee Hybrid . 

Can we over ride the value of the property set in proxy level in run time . 

Example : 

proertyset config (general)

name = patty 

I would like to change the name in run time 

propertyset.general.name = patty,smart
