contract terms template LOV when contract is Global and different from negotiation BU

Summary:

We have many contract terms templates configured in the terms library. They are all created under the US Business Unit (which is the main BU) and all enabled as Global.

When we go into sourcing and creating a negotiation in the US BU, we can see all of the terms templates in the LOV when we create terms.

However, when we create a negotiation in a different BU, we can see the contract types but none of the terms templates appear in the LOV.

I am trying to determine what configuration is required to have a global terms template show up in the negotiation terms template LOV when the negotiation BU is different from the BU under which the terms template was created.
