Conditional redirect?

Subject of the issue

I'm scraping a page that requires the user to click on a "thanks" button before I can access the info I'm looking for.
If the page has already been "thanked", an "unthank" button will be shown instead. I don't want the scraper to click on the "unthank" obviously.

Right now I'm using a code of this kind:

const x = Xray({
  filters: {
	// this filter makes the "thank/unthank" URL call become always a "thank" call
    // doing so I avoid to unthank anything that was previously thanked
    grateful: url => url && url.replace('withdrawthank', 'thank'),
  },
}).driver(driverWithAuth);

x(
  websiteUrl,
  '.subject > div > span',
  [
    {
      title: 'a',
      url: 'a@href',
      magnets: x(
        'a@href',
        x('.thank_you_button:first-child a@href | grateful', [
          'a@href',
        ])
      ),
    },
  ]
)

The problem with this setup is that I will always have to navigate to an additional page even when the page is already "thanked".

Ideally I'd like to be able to tell x-ray to not navigate to anything but just stay in the same page if the provided URL is maybe undefined or false.

Doing so I could have my filter do url.includes('thank') ? url : false, which will make the scraper hit the thank call only if needed.

Is it possible? If not, could this be added?

Can your share here (or DM me on Twitter) the url of the site in question?

Any solution for this?
I am in the same situation, if there is a result or if not, then i can decide what to do in the filter, ie:

//my filter.js
export.isThere = (value)=>{
    return typeof value === undefined || value === '' ? value : ' No value';
}

x('sample_url','body',[{
  title: '.title | isThere ',
  description: '.title+div | isThere'
}]);

Thanks!
