From my stats about 1% can come from the shorts related videos link. 1% is heaps better than nothing esp if its done automatically

100% necessary! This is what the big YouTube educators teach as a first step to get into YouTube you have to post shorts that link to the longs just like some of the software they use does.

Very important for youtube shorts scheduling ^^ thanks in advance

Yes! This should be prioritized honestly.

It can’t be THAT hard to add but man it would save time for everyone that clips videos.
