Multiple Values into a single cell

Hi all,

I'm using excel in lieu of developing a database or using ms project. My list is about 50 projects. My list is essentially a list of projects with status column, timeline info, and description of project. I now want to add resources to each project. The resources are the same set of folks across projects. For example

Project 1 has Tom, Joe, Carl, on this project
Project 2 has Tom, Joe, Cindy on this project

I'd like to create a table with the list of resources and then select multiple values, so that the 3 names appear in a single resources field. Any suggestions?

Thanks in advance
