How to map a Perforce depot's folder to an arbitrary local folder?

I have the following structure on the Perforce server:

MyDepot
  + MyProject
    + MySubProject
      + trunk
        + ... trunk folders/files ...

I have my Eclipse workspace for MySubProject in:

C:\Users\<my username>\Documents\eclipse.wkspcs\MySubProject

If I get the latest revision with a Perforce workspace of:

C:\Users\<my username>\Documents\eclipse.wkspcs\MySubProject

I get:

C:\Users\<my username>\Documents\eclipse.wkspcs\MySubProject\
  + MyDepot
    + MyProject
      + MySubProject
        + trunk
          + ... trunk folders/files ...

I'd prefer:

C:\Users\<my username>\Documents\eclipse.wkspcs\MySubProject\
  + ... trunk folders/files ...

Can I achieve this and if, how?

I found the P4V manual page Defining a Workspace View but it doesn't seem to cover what I want. (There's a garbled sentence under point 2. but this isn't essential in this respect, is it?)
