@william-- Thanks for sharing your thoughts on this! I didn't know the assignment consolidation until now, so that's helpful. While it didn't solve the problem, it did make me think a little differently and I was able to figure it out, so THANK YOU.
A little more detail on the problem:
- A project is opened and there are 10 tasks assigned to "Brand Strategist" role.
- "User A" with a Brand Strategist role is bulk assigned to the tasks.
- "User B" with a Client Strategist role is added to the tasks to provide support to the Brand Strategist.
- A new secondary role for "User B" of Brand Strategist is added to their user setup.
- Need a way to reassign "User B" from Client Strategist to Brand Strategist.
- Note "User B" has actually completed some tasks as a Client Strategist and only certain tasks need the role swapped.

Here is what I did:
- Created a project filter to only show tasks that were In Progress or New PLUS that had the Assignment User = "User B"
- Bulk edit those tasks to change the Assignee's Role for "User B" from Client Strategist to Brand Strategist
