Any way to set\influence Form's default member selection

Hi,

In Forms, where a dimension is in Page and a portion of the dimension hierarchy is permitted that the user can choose from, the default selection (as far as I can see) seems to be the first lowest-level member at the bottom of the permitted hierarchy.

This is of course extremely inconvenient because on a form often you would like to start with seeing the overall picture, ie the top-most permitted member. Instead users are presented by default with a low level member and have to go through the clunky selection process to get them back up to the top.
