How do I show multiple Media Sources in TV file browser?

I have created a second media source called “Media Repository” that shows up in the Files tab on the left column and also in the Media>Media Browser page at the top bar, but both sources do not show in the file picker on template variable fields using the File input type. Just the original Filesystem media source shows up.

I did find the Media Sources tab on the TVs configuration page that lets me toggle from Filesystem to Media Repository, but I can’t choose both at once.

Is there a way to have both accessible at the same time in the file browser?
