In my launch file I spawn multiple controllers, some of which share the same resources. The typical why of loading controllers is to spawn them. What I would like to do at the moment is to spawn all controllers but only have one of them running. Bellow is an example:

<node name="controller_spawner" pkg="controller_manager" type="spawner" respawn="false" output="screen" args="--stopped joint_state_controller controller_1 controller_2/> 

In this example all controllers will be loaded but stopped (because of the --stopped argument). What I would like is that jointstatecontroller is spawned and running whilst controller_1 and controller_2 are spawned but stopped.

Is there a simple way of doing this in the roslaunch file ?

-- Edit -- One way to do it is to launch two spawner nodes like this:

<node name="controller_spawner_js" pkg="controller_manager" type="spawner" respawn="false" output="screen" args="joint_state_controller"/>

<node name="controller_spawner" pkg="controller_manager" type="spawner" respawn="false" output="screen" args="--stopped controller_1 controller_2/> 

Now I have the jointstatecontroller launched and running whilst the other controllers are running but stopped. However I have two spawner nodes which seems redundant. Is there a better solution in which I am left with only one spawner node ?
