Organizing Sponsor Logos for Event Print and Media Use

We are event organizers and to fund the event we create signage both in print and digital formats to promote our sponsors during the event. Signage can come in many different sizes for many different uses and can be a singular sponsor or be a logo wall anywhere up to 100+ sponsor logos. It could also be included in a logo loop for a video. During the 6-months of planning for our events we regularly Add, Remove, or Change around sponsor levels of a company. Showcasing a sponsor logo is ultimately very important and missing one is a terrible occurance. The problem occurs when there is an update of a sponsor and needing to make that logo change across the many different files we have in Adobe Illustrator and After Effects which are our primary platforms for creation. Having to make adjustments to every single file to add one logo can be time consuming. How can we work more effectiantly by updating one document and linking the works to that one file.
