Just because it will add MUCH more complexity to view designer that will make it unusable for beginner programmers.
Professionals recommend to create views programmatically using 'CREATE SQL VIEW' command. With use of 'DBSETPROP' functions for making view updatable, of course. By such way you can create view with any SQL query. VFP View Designer covers only ~5% of all query combinations that may be used for views.
HTH.
