Facebook Custom Conversions & Offline Conversions

Hey Guys, 

Can we please have Offline Conversions added to the available metrics? 

Also, in the case that we want to build a dashboard via Data Studio that displays campaign data that's able to be filtered by date and campaign, it's not possible to report against an individual Custom Conversion. 

As it stands, you can identify Custom Conversions by displaying Event Types, and linking the Custom Conversion ID from FB to the columns broken out, but it's not possible to assign this to a campaign / date. 

This is limiting us in reporting core KPIs for our clients. 

Thanks for your help! 

Paul
