Replace Clip?

I would like to drag a clip from one track and have it replace a clip on another track of the same length. Doing this mixes the clips– is there a way to have it replace the existing clip?

Thanks,
Brian

In the Insert tab of the Ribbon Tab in the montage there is an option to “Replace Audio File” which allows you to select a clip and choose a new source file, but I don’t know of a way to simply drag a clip and have it replace another clip, but maybe somebody else knows a trick.
