Replicate single item

Is it possible to replicate single item? I want to deal with replication & save conflicts between replicas. I want to replicate a ‘lock’ (single field) among servers and then to check for the presence of this field.

The standard ‘document locking’ is not working in my case, because I am doing some RT filed updates, where the document is pending between edit/normal mode causing this feature to be unstable (lock is not being removed correctly)

Thx,

Juraj
