Dashboard: User Variables

Summary

Does every user have to select members for user variables in order to use the dashboard

Content

We've created 2 User Variables (FcstPeriod1 and FcstPeriod2) so that we can compare the Revenue of 2 different periods in a dashboard. 

When a user wants to view  the dashboard he/she first has to go to the  "User Variables" screen and choose members. Is there a way for the admin to set "default user variables" so that not every user has to go through that process? Otherwise I am expecting a ton of trouble tickets (...since users don't like to read manuals and ignore emails...)
