Solution is imported as "update" instead of "upgrade" and there is no option to do an "upgrade".

Using import solution, there is no option to import it as an "upgrade" (i.e. where items not present in the solution are deleted from the environment). -- Instead it seems to be forcing an "update" (i.e. only new and changed are added; but items not present do not get removed).

Please add the option to do an "update" of a solution. So that removed objects are properly removed from the target environment.

Here's an image of what I'm talking about (see below). -- And to be clear: I don't want to stage it for an upgrade and then upgrade it as a second action -- that would double the size and complexity of my script. -- I just want to import it as a (non-staged) upgrade and be done all in one step. -- Like just with an extra parameter to the import solution action.

Thanks!

Start by locating the import solution action and its supported parameters, then review how it currently handles update versus upgrade behavior. Done means a non-staged import option can remove solution items absent from the target environment in one action; clarify the requested terminology before implementation.
