Currently, no.

Yes, it uses WinPcap, but that's not the issue.  As far as I know, no packet capture mechanism directly provides that mechanism; I infer from a statement on the Network Monitor blog that Network Monitor, for example, looks up TCP and UDP packets in the OS's TCP or UDP socket tables to *attempt* to relate packets to processes.  Wireshark doesn't do that.
