One of the things I tend to do in my Bible is visually link things on the same page, or facing page.

this is a terrible example, but happened to be where I was reading at the time I thought about it.
Is there any way in L4 to link ideas (similar thoughts) together visually? I know I can highlight (which I did with a red underline in this case), but I like to then connect the highlighted areas together when appropriate.
Thanks
