Save file widget as the current load file widget?

There is a load file widget that I’m using and works fine.
There is not a save widget, but I can make it work using the load file widget and works also fine. I can save files . But because it wont allow text input, I can only overwrite previous files.
Is there any option to allow name input and I can create a new file instead being forced to only overwrite?

You can link that widget with an input widget to achieve that.

I'm not sure to understand, the file widget only selects a file or folder and returns its path, it doesn't save nor load anything really.
