Report builder 3.0 - separate grand total section to a new page

Hi!

   I want to find out, is it possible to separate Grand Total of a sub group to a new page?

   I tried using advanced mode, find the first line the Grand Total section and set its "RepeatOnNewPage" to true, but, when I execute the report, it will throw an error something like the value of RepeatOnNewPage of the TablixMemeber must be the same as its previous object.

   I need my report pages to separate by subGroup(SubGroupA, SubGroupB, A+BTotal).

Thanks in advance!
