jQuery .on multiple events and selectors

Question

Currently, I have a cached variable, $this, on which I'm applying .on to respond to various possible types of behaviour triggers.

$this.on('click','.trigger a',rowTrigger);
$this.on('click','.actions nav a',rowAction);

In the jQuery .on Documentation it doesn't mention if there's a way to combine the above two into a single call. For example, something like this might be nice:

$this.onAny({
    click: [
        {'.trigger a':rowTrigger},
        {'.actions nav a':rowAction}
    ]
});

Is there a way to achieve this kind of statement (e.g. an existing plugin to extend .on)?

UPDATE

Use Case (in the current code, prior to a nice solution):

// Plugin 1:
function addTriggers(){
  $this.find('td:last').append('<span class="trigger"><a href="#"></a></span>');
  return {selector:'.trigger a', event:'click', target: $this, callback: rowTrigger};
}

// Plugin 2:
function addInlineNavigation(){
  $navCode = '...'
  $this.find('td:last').append('<div class="actions">'+$navCode.html()+'</div>');
  return {selector:'.actions nav a', event:'click', target: $this, callback: rowAction};
}

I'm not aware of one. Would be nearly trivial to write. I'm not seeing much advantage to it, though, compared with chaining:

$this.on('click','.trigger a',rowTrigger)
     .on('click','.actions nav a',rowAction);

But again, the plug-in isn't complicated. Here's an untested rough draft:

jQuery.fn.onAny = function(options) {
    var eventName, eventSpec, eventEntry, selector, i;

    for (eventName in options) {
        eventSpec = options[eventName];
        if (jQuery.isArray(eventSpec)) {
            // Your example, where each event name has an array of objects
            // keyed by selector, where the value is the handler
            for (i = 0; i < eventSpec.length; ++i) {
                eventEntry = eventSpec[i];
                for (selector in eventEntry) {
                    this.on(eventName, selector, eventEntry[selector]);
                }
            }
        }
        else {
            // Assuming just a straight handler here
            this.on(eventName, eventSpec);
        }
    }

    return this;
};
