Pre-process segments with dynamic value (no replies)

For a site of mine I track banner stats through the customVariables. I request these stats through the widget on our control panels. This works but performance is getting bad because these segmentations are not pre-processed by the archive task.

Is it possible to pre-process segmentations that contain a dynamic value? For example:

customVariablePageName1==Banner_511,customVariablePageName2==Banner_511,customVariablePageName3==Banner_511,customVariablePageName4==Banner_511,customVariablePageName5==Banner_511;customVariablePageValue1==Impression,customVariablePageValue2==Impression,customVariablePageValue3==Impression,customVariablePageValue4==Impression,customVariablePageValue5==Impression

In this case the custom variable Banner_<NUMBER> is dynamic.

What would be a good solution to solve this problem?

Thanks!
