How do I supply arpack drivers with all starting vectors?

[Jimmy and Bimmy]

I am using arpack (the dsdrv1 driver) to iteratively solve the eigenvalue problem

Ax = λx

I am interested in the first m eigenvectors, and I have very good initial approximations for these vectors, so I would like to use my m starting vectors as an initial guess. However, http://www.caam.rice.edu/software/ARPACK/UG/node29.html, which is fine if I only want one eigenvector, but doesn't help if I want more than one.

Does anyone know if arpack will let me use my m initial guesses as starting vectors?

If I'm reading the material on those pages correctly, the program only needs one guess vector and returns all of the eigenvectors as columns of the matrix V.
