Provide the destination object in a PreCondition overload

[jez9999]

I want to implement a side-effect during my PreCondition mapping of setting a boolean on the destination object, and it has to be done at the PreCondition phase because it depends on the order of the objects being traversed starting from the initial object and expanding into referenced objects, in that order. At the moment there is no overload lambda of PreCondition that gives me access to the destination object. Could we add one?

A PR is welcome. Similar to this.

Yeah, I was thinking it looked pretty simple to pass in _destination - so much so that I wondered whether there was an architectural reason why that overload didn't exist. Like, is it just building a graph of booleans of "whether to map this member" at the PreCondition stage, so the destination object hasn't been created yet, or something? Or is it just an oversight?

Check the execution plan. But other than that, it seems fair that who needs the overload should implement it :)

Created PR.
