2 isp, 1 ssid routing to certain isp

i have managed running 2 isp load balancing and fail over with 1 SSID on mikrotik RB750. problem is, first ISP can’t run netflix. so i need users who are connected to wifi and using netflix, will route to 2nd ISP, otherwise utilize load balancing. how do i manage this ? btw: 1st ISP is 100 Mbps and 2nd is 10 Mbps.

thanks in advance
