Default Columns on Time Entries Tables

Is it possible to set the default columns of tables showing time entries?
I added some custom fields to time entries, but there is no way to enable them in the time entries tables, e.g. the "All Times" view.
Of cause, I can select them by setting the options on this page, but the next time, I visit the "All Times" view, the column has to be selected again.
Any ideas?
