Designation display next to the part number in the design tree

Hello

We have just taken a big leap from Inventor 2011 and Smarteam to Inventor 2018 and Vault multi-site.

Previously, we had the part number followed by the designation in the design tree of an assembly (Assembly column in Model). A designation is more meaningful to a designer than a number.

How can we also have the visible designation next to the design tree without having to have the extended Vault tree on the screen, which has the number and designation (display choice possible), but which eats up a lot of space on the screen?
