Batch updating for CC libraries?

All latest Adobe app. MacOS

Libraries are very convenient for placing art. However, there's no autoupdate files.

Here's my specific issue. 

1. I export a bunch of photos from Lightroom,
2. Batch them with Photoshop to CMYK
3. Add to Library
4. Use them in InDesign and Illustrator
5. Need to make global changes in LIghtroom
6. Export again, Batch to CMYK again

Theres no connection betweent the new and old. There's no way to batch update 100 images. It's only one at at time. The only thing I can do is

1. Delete them from the Library
2. Readd them
3. Manually update EACH broken link.

It's too time consuming. Because I know I'll need to change my images this way it makes more sense to not use a Library, place images the old way, and just let it find updated links when the files have changed. 

It's fine if you want to edit one file. But what about when I need to edit them all, globally, in Lightroom, NOT photoshop? There's no way.
