Sparse checkouts automation

Hello,

Suppose you have a layout like this:
/trunk
    /dir1
       /dir1_1
          file1.txt
          file2.txt
       /dir1_2

Is there a way with one command to sparse-checkout al the elements
of the path to file1.txt (included) but no more than those elements ?

That is, the local working copy should look like this after one command:
/trunk
   /dir1
      /dir1_1
         file1.txt

Note that file2.txt and dir1_2 won't appear.
