Custom

Is it possible to create an alternate <?php comments_template(); ?> to use on one specific page?

What I would like to revise:

-Change “Leave a Reply” to “Leave a Testimonial” (don’t want to alter the normal <?php comments_template(); ?> as other pages depend on it, but rather create a duplicate which is used only on my testimonials page)

-Have it post the submissions as blog post within a specific category.

Not sure if this is possible or not, just trying to think of a way to create a way for people to leave testimonials, only capture the excerpt on the main page, and have that link to the testimonial in full on a single page.
