Can I Apply Conditional Formatting to All Columns of a Calculated Item?

I have a budget & forecast vs actuals table as shown below.  Actual, Current Budget, and Current Forecast are Version Type dimensions that are associated with the Version dimension as properties.  The 5 columns within the red box are calculated items.  I applied conditional formatting to the variance calculated items.

However, when the month changes, the formatting goes away as shown below:

The intent for the above views is to associate the month dimension with an application variable of “Last Closed Actuals Month” - dynamically updating to show stakeholders their monthly and YTD variances.

Is there any way to apply the conditional formatting across the entire calculated item?  Or a different approach to BvA views entirely?  The approach shown above contains 6 conditional formatting rules (3 columns x2 rules each), so doing this for every month doesn’t seem viable.  Thanks!
