Lack of interest Warnings - Possible to record warnings to a folder, ala vB?

[MGSteve]

With our vB setup, any warning issued are recorded in a seperate folder and any warnings for the same user are grouped within the same thread. I don't know if this is standard vB or not, we've had it for ages.

Is this something that can be added into the standard XF warnings system as an option, as we find it very useful as a snapshot of who's been bad and who we need to keep an eye on.
