@jessicaramirez Unfortunately, only specific objects in Workfront can have a custom name (Portfolio, Program, Project, Task and Issue). This article provides additional information regarding the list of objects where customization is possible.
It looks as if there is already an idea for additional customizations of terminology, so I'd recommend you up-like that and post a comment for your specific use case. I'm also happy to re-surface this to the Workfront Product team for additional consideration!
