I believe that with compiled sitemap as well as treeprocessor you
can't do it through the sitemap.

However, you could write an action that dispatches other
actions. Afterall, actions are just avalon components and they share
the same component manager to some extent. Your action would need to
be composable to get the component manager instance needed.

But watchout: This custom action needs to be declared in the very
sitemap you want to use it, since this way it would inherit all
components from managers of ancestor sitemaps. Obviously, as long as
you don't access components declared on subsitemaps this could be
relaxed to declare the action on the same level or below the one your
other actions are declared.

If you were using the flow layer in 2.1-dev, you could do it from
