It is crazy that it is specifically mentioned in their collateral, but you can't score in that way. I wonder how much it would impact the platform to run percentage calculations. There has to be a reason they haven't rolled it out.

Just thinking about this, while it wouldn't be ideal to take out of Marketo, it's got to be possible to do in SFDC... I'm going to work with my SFDC crew tomorrow and see what we can come up with!
I was thinking the same thing about Salesforce Dory. Let us know what comes out of that meeting.
