Is there a way to upload any additional documents even if the form being filled out doesn’t ask or have a spot for additional uploads ?

Hello Ari,

I suggest you to add another upload field just in case the user wants to upload additional documents. Just make sure it's not set as required so that it would be optional only.

If this will not meet your requirements, please do not hesitate to tell us so that we could provide another workaround.

Thank you.
