It'd be cool if you could select all linked comps from the project panel and from within there ask it to render and replace all linked comps in a sequence. That would be incredibly helpful.

You select all linked comps from the project panel and then with control click select a feature that allows you to render and replace all linked comps within a selected sequence . instead of manually having to select every linked comp in a sequence and ask to render it do a batch render and replace so you can save hundreds of hours , especially for people like me that use a lot of linked comps in premiere.
