If I correctly understand your question, disabling or setting the BatchRequest option located on the WFM Server to false should resolve your issue.
BatchRequest
Default Value: true
Valid Values: true, false
Changes Take Effect: Immediately
Dependencies: None
Specifies how WFM Server processes multiple time-off requests submitted simultaneously by a single agent.
If this option value is set to true WFM Server processes these time-off items in one batch. If set to false, WFM Server processes these time-off items one-by-one.
