How to disable slideshow's thumbnail toggle feature

Hello,

We are using the slideshow  feature to show images on our site page. We have "Show Next and Previous Controls" and "Show Thumbnails" enabled. However, my client would like the "Show Thumbnails" feature to be enabled WITHOUT giving people the ability to click on the thumbnails to move from image to image (basically the thumbnails cannot be clicked on). Is this possible with code?

Thank you for your help!
