Render multiple seamlessly looped stems

I am currently working on a video game track. The music needs to loop seamlessly, and I need to export all the instrument tracks separately (each have to loop seamlessly too).

What I’ve done so far is use Render in Place to create new audio tracks with tails for each instrument, but then I’d have to cut every single tail, put them in a new audio track, create group track for each instrument and then use batch export. It’s getting frustrating with so many instruments, and this is only 1 piece of music.

Is there a faster and better way to create looped stems?
