Inter-Site - Warehouse by default

Hi,

Is it possible to add a Warehouse by default inside the intersite rules 's grid ?

Exemple : Site A orders to the site B.
The customer want to use a "Transit" warehouse when the truk leaves the other site (site "B" for exemple).
When items left the site "B", it can take hours /days (dipend on the distance) and items are not in the site "A" yet.
Only when items arrive physically in site "A", users will realize a Transfert from "Transit" warehouse to "Stock" warehouse.

I know we can do it by duplicate the WMS journals and use the Warehouse by default with the journal, but we have already so many journals...

Thanks
