Hello all, I want to implement the File upload functionality with validatio

Hello all,
I want to implement the File upload functionality with validations in the file name. My validation is - The following characters are not accepted for file names. \\ / ; : "
I see that Appian is using this functionality to validate the file name while uploading any document under Documents/Upload New Document, and I want to implement the same functionality.
I tried to configure my Form using 'File' option in the Standard inputs. But unfortunately couldn't set the validation for 'Name'. Can any one help me in setting up the validation please.
I tried to implement it using masking for the Text, but no luck with it - got different issues with longer texts.

Thanks in advance.
Regards,
Sunil...
