Increase default rows at a multipage dashboard

[bobstoelinga]

When using a portalpage, in combination with a multipage dashboard, Cognos by default only shows 10 rows per page. It is not possible to change this parameter within the portal options.

But, I use a navigator dashboard within the portalpage, than it is possible to change the default number of rows.

When viewing the html code through Google Chrome I can see the parameter maxObjects = 10 but i can't modify it anywere.
Does anybody know if on the cognos server there is a xml file in wich to change this?
