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

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 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 .

Add the required string to the Studies.js parameter part of the platform/core,
If you also add mappingFilter in StudyListRoute.js of platform/viewer to match, user can send as params when loading studyList.
