are we relabeling is now the "new beta" dashboard the "Standard Dashboard" going forward? if so, I would caution that confusion may result, since the dashboard that is being replaced is often referred to as the Standard Dashboard now.
I hesitate to make any suggestions, since I haven't yet seen a UI mockup/used the feature in a sandbox, but possibly  "If you are using this dashboard because you cannot find the same feature on the other dashboard..." (?)
