HU GR Message Inbound Delivery EWM

Hi Experts,

If in EWM inbound delivery I have created multiple HU's and warehouse task for each HU for putaway.

While confirming using RF-Putaway by HU option, one GR message is getting posted for 1 HU.

Can you please suggest, is there any way to control this. We would like to see the single GR message when putaway WT's are confirmed for all handling units.

Thanks in advance.
