Specify source IP for management VDOM traffic

[Dave_Berger]

Is there any way to specify a source IP for management VDOM traffic (e.g. FortiGuard communication, DNS lookups, etc.)?

I believe the source of this traffic is always the interface from which it leaves. If your management VDOM is in transparent mode then it will always be the management address of that bridge. If your management VDOM is in NAT mode then the source address will depend on the destination.
