Unique Question Limit: the option to have inline detection of duplicates in the form

One quick question I want to ask regarding the setting of "Unique Question"   Do not allow previously entered values.

I have enabled this setting and selected the phone number as a Unique question but we only come to know about this when we complete the survey and click on submit button then it displays that only one entry is allowed. 

What i am looking for is that when we enter the value in the phone number at that time only it display that message not after clicking the submit button. 

If this setting can be possible it will save our lot of time as well as efforts.

Looking for any positive response from your side

Regards,

It's not possible, unfortunately. Let me escalate this thread to our backend as a feature request. Unfortunately, we cannot give you an estimate as to when this feature will get implemented or if our developers will consider adding them in the future, but as soon as we have an update, we will let you know through this thread. 

In the meantime, you may consider using the current settings. 

Thanks for your quick response. Kindly add this as a feature request on my
behalf and provide me the link of that feature request so that i can also
have a follow up on this because we really need this feature to be added in
our form.
