Google Chrome Portable Multiple instances are merging into a single icon on the taskbar

Hello,

I am using multiple instances of Google Chrome Portable and they are merging into a single icon on the taskbar.

I think it's likely because they share the same application ID. Windows groups applications with the same ID under a single taskbar icon to save space.

How can I run Multiple instances with each separate icon of Google Chrome?

I also have attached the screenshot image for easy to understand.
