Do you use Tokens for global user friendly campaign content?

I'm trying to build an automated sales campaign which references the most recent asset (in real words rather than my campaign naming structure names) to the individual that runs at a global level and references individual campaign.  I'm guessing best way to do this is with tokens but not sure how to get started on creating that structure. Sample copy below. Support didn't have much feedback on how to do and recommended I ask here. 

"Thank you for your recent interest in (<insert token: most recent piece of collateral> example: Best White Paper) from our company."

Are you doing this today?  If so how have you built it?

Thank you!
