Multiple shipping number for one order

[Kedz]

Hi,

I would like to show multiple tracking number for one order in the order detail tab.

I tried to insert two row in order_carrier with the same id_order, and it work for 1 minutes (i got two line in the carrier tab of history detail) then it went back to one line.

It worked for one minutes this morning so i'm sure it possible to display multiple lines (there is a foreach in the template).

Thanks in advance
