Every task that is created within the Request Form should contain a unique ID in the title (can be configurable), no matter if there are mapped responses or not.
For example, a title should look like this: [UniqueID] - [Name]
The unique ID is generated automatically, whereas the name is an answer to one of the request form questions, which is set as 'Title'.
Unfortunately, currently it is only possible to choose between a default title where a unique ID is created or a custom title which is generated by the answers within the form.
