Is repacking of Hus possible after creation of outbound delivery

Ok i have got an issue where the Tus is loading completed and the user is doing goods issue

I m getting an error saying "

This is a cross functional Hu and loaded to two different tus with different line items of same delivery

now they are trying to assign the same hu to new tu and we are getting the above error

now the outbound delivery is also created for the same hu and the new tu is unable to be departed

what could possibly be the solution. repacking of the items to a new hu and im not sure if thats possible after creation of outbound delivery

hu has two seperate delivery ref attached to the same tu . if that is not the solution please advise

Thanks
