How to not show Column Summary and Row Summary as total per default in crosstab?

Hi,

I create new Adhoc Report and choose Crosstab.

As soon I have selected some fields, the totals are shown as default.

I now have the option to "Delete Column Summary" respectively "Delete Row Summary" (see pic below).

Question:

How can I set this Option as Default for every Crosstab I create via Adhoc Reports?

So I will have the option to add the Summary but initially the crosstab will be shown without total row/column for each attribute.

Thanks for any hints.

(Customization in files will also be acceptable, if this is not an official setting via GUI.)

Regards

Christoph
