Witelist randomly located VPN service application.

I use Private Internet Access VPN service and I connect via their client, which generates rubyw.exe which is located in random directory (better explanation: https://support.privateinternetaccess.com/index.php?/Base/Search/Index ).
I need either ability to modify ruleset to ALLOW an app to run an executable or add above mentioned app/process to whitelist WITHOUT location, just by process name. Please help, it’s annoying issue. Thank you

I made a video for this once, you can find it here: Allow an Application to Launch Another Application With a Changing Path (CIS)(HIPS/BB) - YouTube

Thank you very much, it saved my nerves.
