Is there a way to upload plugins to your Aternos Server like Server.pro? And if there isn't can you add one?

So i have a choice between Server.pro and Aternos. Server.pro has plugin uploading and Plans. While Aternos is free for everyone. SO i decided to go with aternos. And I noticed that you can only make files and folders. So, I would like to request that you should add a plugin uploading like server.pro. Because you don't have every plugin. And so the players can choose what plugin to have. There will be more plugins because the customers can go over to the bukkit and spigot website to install these plugins. Thank you Aternos if you do add it. I will be really apprecieated.
