Number format changes in Calc pivot tables

In my pivot table, I set the numeric format on the whole sheet (containing the pivot table) to 2 decimal places. If I change the Page Field to another selection, the format in the pivot table reverts to general. Is there a way to overcome this?

I am using Calc 3.5.7.2 (Ubuntu 12.04).

Thanks in advance.

Same problem here.

Theoretically, if you want change the format heritage from source data, you can change the styles for Pivot Table Menu/Format/Styles&Formatting the styles with the name beginning with Pivot Table.
But seems that it doesn’t work actually. I have reporting a bug pending of confirmation, fdo#64440.
I know that Kohei, a great developer, who usually solves the Pivot Table issues, is doing a deep work on the scalc core code, so maybe we need to be bit patients waiting for a solution.
