Using composer vimeo in admin view

[vfxhost]

Hello!
I'm moving my question from the old forum here, since I had no answer.
I use Admin View custom PHP postSaveHook Method to get thumbnail_url from vimeo based on vimeo_video_url field value and store that information to the database.
To get the data from Vimeo I am using composer.
So, I need to add the following to the top of controllers/myitemview.php, manually to make my code to work.
require JPATH_SITE.'/vendor/autoload.php';
use Vimeo\Vimeo;
Is there any way to do it from JCB?

We have been working on a pro/feature to give access to update the headers of the model and controller per/admin view. We will then also target all files eventually. This release should come out this week hopefully. So if you are not already a pro/member then subscribe and get early access to pro/features.
