Tip - Marriotts along a travel route?

Is there a way to search for Marriotts along a travel route?  I thought this used to be an option on the Marriott site, but I can no longer find it.  For example, we are driving from Seattle to Palm Springs.  It would be great to see what Marriotts are available along the way.  We will be doing more of this type of travel...driving instead of flying...so it would be great to be able to plot our Marriott stays along the way.
