Design Program Recommendation Needed

I’m looking for a program to build large womenswear design development decks and have found that my team is always sacrificing something and struggling with technology

It has to be able to handle:
-40+ pages
-hundreds of illustrator sketches + jpgs/pngs + text
-ability to move around images/sketches quickly
-aesthetics crucial
-live doc that multiple team members can use simultaneously

Have tried Illustrator + Powerpoint (live Office 365 doc).

Any help would be greatly appreciated!!

If you use jpegs/pngs, etc of the illustrator sketches- try creating the file in Google SLIDES. Then make the file shareable & editable with the team.
