OTM 6.4.2 - Change Combination Equipment Assigned to a Shipment

Hello,

I am using combination equipment. OTM create a shipment and automatically assigned a initial equipment and a combination equipment. I need to change this assignment manually.

I select the shipment and use the action  "Change Equipment Group", using the manual option and the search display list shows only the single equipment groups.

If I select the option "Optimize", OTM assign another combination equipment but not the one I require.

Do you know if is possible to select manually the desire combination equipment group?

Thanks for your comments.
