How do I go back say one year, run a scan from then, and then see current results now-results like I get on watchlist tracking?

Within Blocks, use the Settings tab (sub tab under main Strategy tab) to define the scan period as 1 year - as opposed to All History, which is the default.

Under the Conditions tab (also a sub-tab under the main Strategy tab), define your scan conditions using the Add Condition library.  To find the resulting list of stocks, click the green funnel next to the Strategy tab, wait for the calculation to take place, and click Results to see all the stocks that are currently meeting your conditions.

Hope that helps-
