In the work on {T205754}, we are adding logging to page views. We would like to understand when users are clicking on links provided by the [Czech welcome template](https://cs.wikipedia.org/wiki/%C5%A0ablona:V%C3%ADtejte) and [Korean welcome template](https://ko.wikipedia.org/wiki/%ED%8B%80:%ED%99%98%EC%98%81%ED%95%A9%EB%8B%88%EB%8B%A4).
What we would like to do is append a query parameter to all links that are included on those welcome templates. The query parameter will be the same for each link, and it should read `fromWelcomeTemplate=1`. This way, in our EventLogging data for the Page Views schema, we'll be able to clearly see when users are visiting help resources from these links.
As an example, in wikitext, this looks like `[{{fullurl:Speciální:Userlogin|fromWelcomeTemplate=1}} vytvoření účtu]`. That renders to `https://cs.wikipedia.org/w/index.php?title=Speci%C3%A1ln%C3%AD:Userlogin&fromWelcomeTemplate=1`
@revi and @Urbanecm please let me know if you will need more information from us on this.
