Request for complex file upload support

[sss2sssss]

Is your feature request related to a problem? Please describe.
Currently we faced some issue for custom made multiple file upload interface where the file input is hidden


The "Upload File" keyword will not working on this condition (if we try to use external layer it will show Error: Node is not an HTMLInputElement; if we targeting on the file input it will waiting the field to visible until timeout)

Describe the solution you'd like
I think we need to have some sort of complex file upload mechanism (maybe add option on "Upload File" keyword)

Describe alternatives you've considered
Or maybe completely different keyword on this

Additional context
Refer to the screenshot attached above
