Self-defined path and name of the directory

Is your feature request related to a problem? Please describe.
If I use many apps on one instance then my main directory in the files is full of folders that are used for the respective apps. With most apps you can define where this folder is located (e.g. in a subdirectory) or what this folder is called.

Describe the solution you'd like
That the function will be added to set itself the location and name of the directory of the app.
