How can I add custom querystring?

I am currently implementing a dicom web server and plan to display dicom images with ohif viewer (v2).

When I request qido from my dicom web server, it gets a good response and shows the study list.

But the result I get from dicom webserver will get full data from dicom webserver in DB.

So I plan to filter via “projectId”. How do I append query string when requesting qido, wado etc in ohif viewer?

For example, the current working qido request url
http://localhost:4001/rs/studies?limit=25&offset=0&fuzzymatching=false&includefield=all
=> http://localhost:4001/rs/studies?limit=25&offset=0&fuzzymatching=false&includefield=all&projectId=abcd1234

I want to add a special querystring like projectId=abcd1234 .

How can I add custom querystring to qido request in ohif viewer?
