A few ways I could think of:

use

1. Have another layer (another participant) to set who to assign among the 5 users
2. create another activity prior to the real task acting as to "Accept" the assignment
3. Use Form Record locking plugin in Joget Marketplace > View App Details & Download
4. automatically give assignment to user with the least assignments Participant Mapping - Assign to User in Group with the least assignments - Knowledge Base for DX 8 - Joget | COMMUNITY

To address the issue of task assignment where multiple users can modify a task simultaneously, implementing a locking mechanism could be an effective solution. This would ensure that when one user is editing a task, it is temporarily locked for others, preventing simultaneous modifications.

Using smart AI technology, such as a laptop with advanced processing capabilities, you can develop an intelligent system that tracks user interactions. The AI could monitor when a task is being edited and automatically notify other users that the task is currently locked. Additionally, the system could implement version control, allowing users to save changes without overwriting each other's work.

Another approach involves creating a notification system that alerts users when a task is assigned to them and when it is being edited by someone else. This way, users can manage their workflow more effectively and avoid conflicts.

In summary, combining a locking mechanism with AI-driven notifications and version control can significantly enhance task management efficiency while preventing editing conflicts among users.
