Flow preferences in a template

[PatWruk]

Something I don't quite understand, hoping someone can shed some light on it.

We have about 50 locations using a template, one of the locations is having some ISP issues at the moment, not enough to fail, but upload speed is only about 2mbps.

Using the flow preferences I'm trying to specify their primary network to prefer WAN2 but it's giving me the error that the IP range does not apply to any configured subnets. 

In the template under Security & SD-WAN -> Addresses and VLANs, that VLAN is set to use a /24 from 10.2.0.0/16.

That location is set to use 10.2.161.0/24, so in the flow preference I'm trying to set just that /24 for that one location, not change all of them.

Is this something that can't be done?

Note:

The "add host" button under Security & SD-WAN> Configure > Traffic shaping > Flow preferences, gives an option to enter a value between 1-254. The following seems to be the expected behavior:

If we have a subnet /26 from 10.0.0.0/8, there would be 4 possible 4th octets: x.x.x.0/26 = .0-.63
x.x.x.64/26 = .64-.127
x.x.x.128/26 = .128-.191
x.x.x.192/26 = .192-.255

Since the template needs to be applicable to ALL networks tied to it, it uses an offset.
If we were to specify the .1 host, this would be the equivalent of .1, .65, .129, and .193 depending on the given network tied to the template.

That makes sense, thanks.
