Is it possible to use RouteRule in ServiceCallOut Policy?

My requirement : In ServiceCallOut Policy, HTTPTargetConnection/URL will changes dynamically based on environment.name. Please suggest best approach.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ServiceCallout async="false" continueOnError="false" enabled="true" name="Service-Callout-1">
    <DisplayName>Service Callout-1</DisplayName>
    <Properties/>
    <Request clearPayload="true" variable="myRequest">
        <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
    </Request>
    <Response>calloutResponse</Response>
    <RouteRule>
        <Condition>(environment.name = "test")</Condition>
        <HTTPTargetConnection>
            <URL>http://test.apis.com</URL>
        </HTTPTargetConnection>
    </RouteRule>
    <RouteRule>
        <Condition>(environment.name = "uat")</Condition>
        <HTTPTargetConnection>
            <URL>http://uat.apis.com</URL>
        </HTTPTargetConnection>
    </RouteRule>
    <RouteRule>
        <Condition>(environment.name = "prod")</Condition>
        <HTTPTargetConnection>
            <URL>http://prod.apis.com</URL>
        </HTTPTargetConnection>
    </RouteRule>
</ServiceCallout>

There is no provision to use routerules in a service callout.

Looking at your example above, it seems like you should use a target server configuration in the service callout and let it handle the environment based backends. You can see more information in the post below.

If you need some conditional routing to be done to multiple backends by using service callouts, an alternative would be to execute your service callout conditionally

<Step>
                    <FaultRules/>
                    <Name>ServiceCallout-1</Name>
<Condition>request.header.abc = "route1"</Condition>
                </Step>

<Step>
                    <FaultRules/>
                    <Name>ServiceCallout-2</Name>
<Condition>request.header.abc = "route2"</Condition>
                </Step>
