Tried doing a callout from an execute method in a queueable class and go the @future error -

Callout not allowed from this future method. Please enable callout by annotating the future method. eg: @Future(callout=true)
07:13:51.752 (8701449752265601)|SYSTEM_METHOD_EXIT|[1263]|System.Http.send(ANY)

Is there a way to annotate the execute with "(callout=true)".

I sounds like what i want to do may be doable if there's just some syntax to get the annotation.
