View elements last updated by... <user>

I was asked to check an interns work recently. She had worked on a project for several days and had been syncing regularly so she was no longer the owner of things. It got me thinking… how could I view all the things she touched? I know Revit has a ‘last updated by’ parameter. I thought of creating a filter but this field is not available within the filter dropdown. Does anyone know if someone has made something like this yet? I imagine the program would list all the users in the project then let you pick the name of who you want to see who is in the field ‘last updated by’ on all elements in the view. Could be useful in 3D and 2d views. I tried creating it but got lost in the sauce.

Not entirely reliable, but you can use the WorksharingUtils

These tools sample ways to use it:
