Laravel route group controller

[shaedrich]

Current situation

I'm using Laravel 5.5 and wonder if I can not only group routes by name prefixes and route prefixes but also controllers since they all use the same controller. The documentation didn't provide anything the like. Here's what I currently have:

Route::group([ 'prefix' => 'my-route', 'as' => 'myRoute.' ] , function () {
    Route::get('/{viewMode?}', 'MyRouteController@index')->name('index')->where('viewMode', '[a-z]+');
    Route::get('/ajax', 'MyRouteController@ajax')->name('ajax');
});

Goal

And it should look something like that:

Route::group([ 'prefix' => 'my-route', 'as' => 'myRoute.', 'controller' => 'MyRouteController' ] , function () {
    Route::get('/{viewMode?}', 'index')->name('index')->where('viewMode', '[a-z]+');
    Route::get('/ajax', 'ajax')->name('ajax');
});

Is there a way to achieve this kind of behavior?

Approaches

Short handing the code bit by using a variable ($controller = 'MyRouteController'; in the group(), then Route::get('/ajax', "{$controller}@ajax")) doesn't make the code much shorter though and would require an additional line of code.

In Laravel 4 there were implicit controllers available by using Route::controller() but that's not what I'm looking for since this won't be implicit.

Another approach would be using Resource Controllers. But I discarded that idea, because Resources are mainly used for RESTful APIs and therefore unnecessary routes are created (unnecessary but not problematic per se). But if I intend to misuse Resources for that purpose I have to supplement the controller upfront in order to achieve that behavior which seems a little messy and undesirable to me. Nonetheless, in general that does work …

Prospects

Anyhow, both approaches are not very satisfying, which brings me back to my original code snippet. If there's no approach which can do what I outlined, is there a fair chance, this could be implemented?
