Keep deployed package name in history after deleting package

Currently , when we ended teledeploy a version of the software , we remove the stats via the button "validate all" and then we remove the package from the server.

On the computer form, the list of deployed package still show the timestamp of the package we remove, but not the name of the package (it is replace by Unknown (deleted package)).

I think it can be useful to keep the name of the package in this history as it is more readable and understandable than the timestamp.
