As an alternative, if you don't want to overwrite the visual
selection, you can append to the visual block with "A" and then paste
the contents of the selection with

<c-r>"

and then hit <esc> which will paste the register after each line. So
the entire sequence would look something like

«visually select text you want to copy»
y "yank that text
«move to the top of where you want to paste»
<c-v> " enter visual-block mode
«move to the other end of the range»
A<c-r>"<esc> " paste the yanked text

You can use the same trick, only with your system selection register
("*" or "+") instead of using the default register (")

For reading it from a file, it gets a little more complex because the
standard EOL marker would also come in, so it would appear as if
you're also adding blank lines to your text. But you could do this
with the expression register. Inefficiently, that would be

A<c-r>=readfile('somefile.txt')<cr><esc>

which reads the file's contents fresh each time. Alternatively, you
could read it in once into a variable (say, `content`), and then
append the resulting contents:

:let content=readfile('somefile.txt')
«do most of the above»
A<c-r>=content<cr><esc>

This all assumes that your destination locations are column-aligned.
If they're ragged, you'd have to do a search-and-replace. Which also
isn't that hard. For your (OP's) purposes, it's pretty
straightforward and can be done in any of the ways above:

:'<,'>s/baseline\zs\ze b;/\=' '.@"
:'<,'>s/baseline\zs\ze b;/\=' '.@*
:'<,'>s/baseline\zs\ze b;/\=' '.readfile('somefile.txt')
:'<,'>s/baseline\zs\ze b;/\=' '.content

The "\zs" sets the start of where the replacement will occur and the
"\ze" set the end of where the replacement will occur, so by having
them back-to-back like in my example, they do an insertion rather
than a replacement. But notice that you also have to add another
space before (or after, depending on where the space occurs in
relation to the "\zs\ze") the content that you want to paste.
