Chrome, dealing with multiple profiles and P12 certificates

[Dennis Reda]

Hi, please point me to a FAQ or answered question, I've looked but can't find what I need.

I'm trying to automate some tests using Chromedriver, and I have multiple profiles EACH with its own P12 certificate for logging into our target web site. For example, ChromeProfileA uses certA.p12 to access the target web site, but ChromeProfileB (with different permissions, etc.) uses certB.p12  to access that same web site. 

I understand the registry entry process to create a filter for one certificate to allow it to be used on a web site, but, I can't see how to select one specific certificate from a list of certs, based upon the profile in use.

Thanks!

Dennis
