Realms file manager

It would be great if you could add a file manager to Java realms. I own a realm with datapacks (Amount varies depending on the world) and have slow internet. I am unable to update the datapacks on my realm without having to download the world and reupload it once I have finished the update to the datapack. This process usually takes between 10-20 minutes (depending on world size. Highest I've recorded is an hour.)

To help all of us with bad internet speed, it would be nice to add a file manager, where you can upload folders and edit the files of the realm. You could add a gui which allows you to edit the realm files (Whether either just being able to delete and upload folders and files, or being able to straight edit .mcfunction files and such.
