maintaining contact group/sort order

generally i like to have contacts displayed grouped in categories, sorted by
first name. i can go into customize and set this up.
occasionally i want to sort the whole folder by first name and then i click
on the full name column.

the problem is that when i want to go back to the category grouping, i right
click on column headingsarrange by categories. then i have to go back to
customize to get the first name sort order.

how can i switch back to category grouping and maintain the first name sort?
