When using the `exec` component is it possible to specify args inline rather than having to set them in the `ExecBinding.EXEC_COMMAND_ARGS`?

For example I have this Route:

```
from("seda:getPolicyListStart")
.process(new Processor() {
    public void process(Exchange e) {
        ClientRequestBean requestBean = (ClientRequestBean)e.getIn().getBody();
        List<String> args = new ArrayList<String>();
        args.add(requestBean.getClient());
        args.add(requestBean.getSort());
        e.getOut().setHeader(ExecBinding.EXEC_COMMAND_ARGS, args);
    }
})
.to("exec:some_command?useStderrOnEmptyStdout=true")
.convertBodyTo(String.class)
.log("Executed OS cmd and received: ${body}")

```

However I would have thought that I could use the Simple Expression Language to simplify it like so:

```
from("seda:getPolicyListStart")
.to("exec:some_command?useStderrOnEmptyStdout=true&args=${body.client} ${body.sort}")
.convertBodyTo(String.class)
.log("Executed OS cmd and received: ${body}")

```

Similar to how you can use File Language (a subset of Simple) when you use the File Component.

Is it possible? If not, can the first example be simplified?

**UPDATE** [solution] :

```
    from(requestNode)
    .routeId(routeId)
    .recipientList(simple("exec:"+osCmd+"?useStderrOnEmptyStdout=true&args=${body.client}"))
    .convertBodyTo(String.class)
    .log("Executed OS cmd and received: ${body}")
    .to(responseNode);

```

Thanks.
