Media encoder Stitched clim names does not work as expected

Hi

I have used the function to stitch clips in ME.

Drag-drop on Stitch button.

Before encoding I changed the rendering option to add the name of the clip(s) on the rendered video.

To my profound disappointment it did not work as I expected 😞

Only the name of the first clip has been added to the whole reel.

option looked so nice to create proxies of B-Roll without dropping them in Premiere.

Did I miss something or this kind of option is still to be implemented.?

Thanks for letting me know

Cedric
