Can I "Add to Reading List" from a link context menu in Safari?

I'm using Safari 13.0.1 on macOS Mojave 10.14.6. I can add the current web site to the reading list by pushing the sharing button and then selecting *Add to Reading List*. Now I want to that **without** opening the page first. So the context menu of a link in Safari has a *Share* menu entry, but there's no *Add to Reading List* in its options. In *System Preferences* - *Extensions* - *Share Menu*, *Add to Reading List* **is** enabled. But it still doesn't show in a link's *Share* context menu. I disabled and enabled *Add to Reading List* to no avail — other entries in there immediately hid and reappeared in a link's *Share* context menu when unchecking/checking them here. So, can I get *Add to Reading List* into a link's *Share* context menu in Safari? If so, how?
