Hello Team, 

We are using Facebook pixel extension to measure the effectiveness of advertising by understanding the actions. Currently we are working with different agencies who provide us different ID's. 

The current Facebook extension accepts only one ID so I'm looking it to customise Facebook extension which accetps multiple ID's and make new develop extension. 

I'm referring to example https://github.com/Adobe-Marketing-Cloud-Activation/extension-facebookpixel

but Have you ever come across this type of scenario or any development touch points? 

Thanks
