Sorting portals by clicking on field headers

[charper]

I'd like to be able to have portals resorted by clicking on header fields just above the protal.

Example: A portal contains the following related fields: F1, F2, F3. Above each field is a text header: "F1", "F2", "F3". When I click on the F2 header I want the portal to be resorted on F2.

It appears that portal sorting is completely determind by the sort option setting in the relationship definition dialog and that this can only be set by interfacing manually with this dialog. Is this true or is there a way around this?

The way around the fixed nature of sort orders and relationships is to setup one relationship and layout for each sort order and to switch to a different layout when the button is clicked. It's takes a little additional work, but the user should not notice the difference.
