Off the top of my head, I can't think of a built-in way to insert a file
before an address (am I missing something?).

One could probably come up with some incantation using multiline
commands (D/G/H/N/P):
https://www.gnu.org/software/sed/manual/sed.html#Multiline-techniques

But I think this one is easier using gawk:

    $ echo FOO > bar
    $ seq 5 \
         | gawk '/5/ { while ((getline tmp < "bar")>0) { print tmp } } ; 1'
    1
    2
    3
    4
    FOO
    5

Or are you asking for a new feature of inserting a file before an
address?
