Netflow for specific SVIs?

Haven't had much luck googling this because I'm not even sure this is possible or I'm wording it incorrectly. Is there a way with a Cisco 6500 series switch with several SVIs configured, to explort Netflow for those specific VLAN interfaces and only send source/dest information in regards to that specific SVI?

Scenario:

Customer A has SVI VLAN 20.

Customer B has SVI VLAN 30.

so on and so forth

Each has a dedicated link directly to the Cisco 6500 connected to a switch on their side (basic layer 2 connection passing their vlan ID). They are routed upstream after 6500 to internet. Simple hub n spoke topology.

The goal here is to export Netflow to a parser (LogicMonitor collector) in this case. These collectors have a cap of 1000 top flows. I want to break this out and have separate collectors for each customer as to capture as much data per collector. Is this possible? Or does Netflow not work like that.
