Add yifysubtitles.org to the list of subtitles providers

As per title, can anybody direct me on how I could add https://yifysubtitles.org as one of the sourceswhen downloading subtitles?

Thanks

That site does not provide a programming API form searching and downloading of subtitles. So it can't be added. Same applies for all other subtitles sites.

It is not possible to add any subtitle websites yourself.

All do respect Nothing not Possible Sir !!
To become the world best codec specialist software any obstacles must be solve.
It is a Tremendous breakthrough if multiple subtitles provider can be added.
The world changer if you catch my drift !!

It will not be done.
