Milestone Log

We recently had a brand hit 1M PVs for the day, and wanted to see the last time a brand hit a milestone like that. We had to pour through older reports and cross-reference them in Omniture, which proved to be a tedious task. 

We'd love to have a milestone log that we can enter in pre-determined milestones (i.e. 1M PVs in a day, 500k UVs in a day), and have all brands automatically update anytime said milestone is hit. 

What is the likelihood something like this could be set up? The data is already there, it would just be creating an interface to capture the marks and list them together.

Thanks!
