+Add support for specifying machine preset at trigger time. Works with any trigger function:
+
+```ts
+// Same as usual, will use the machine preset on childTask, defaults to "small-1x"
+await childTask.trigger({ message: "Hello, world!" });
+
+// This will override the task's machine preset and any defaults. Works with all trigger functions.
+await childTask.trigger({ message: "Hello, world!" }, { machine: "small-2x" });
+await childTask.triggerAndWait({ message: "Hello, world!" }, { machine: "small-2x" });
+
+await childTask.batchTrigger([
+  { payload: { message: "Hello, world!" }, options: { machine: "micro" } },
+  { payload: { message: "Hello, world!" }, options: { machine: "large-1x" } },
+]);

+  { payload: { message: "Hello, world!" }, options: { machine: "micro" } },
+  { payload: { message: "Hello, world!" }, options: { machine: "large-1x" } },
+]);
+
