Receive User response in Alert?

Receive User response in Alert?

Does anyone know if one can receive User Input in Alert?  For an example, I have a stateless form that will have a button say "Generate Data".  If certain conditions exist, I want the Alert to say "Duplicate condition exists, do you want to proceed?" and have a Yes and No type button in the Alert box.  Then based on the user response, the On Click event will behave differently.

Is this possible to do in Creator?  The Alert box seems to be just displaying a message with Ok.  Is there any enhancement pending for this if this is not possible?

Any help will be greatly appreciated.  Thanks.
