Cleardata rule - How to exclude certain accounts?

Content

In our Forecast Cube we are loading the Revenue Forecast to several  different regions (i.e., REV_Region1,REV_Region2, REV_Region3, REV_Region4), these revenue accounts have no associated actuals, but I still want to keep the data for these accounts. Before loading the actuals we clear the Scenario. How can I exclude certain accounts from getting cleared out. The rule is below.
