Yes, those of us who "invented" under the BB routing 40 or so years ago, improvised many solutions using filed, groves, plastic or model airplane tubing, or nothing at all for FD under the BB routing.
RD routing was more of a problem for 2 reasons. The most important issue is that many of our frames had brazed-on chainstay stops on
top of the stay, and so wanted the cable routed above the shell to run clear. Some creatively run it under the BB, and did a half twist coming around the inside of the right chainstay, but it was less than ideal.
If the OP has a clip on chainstay stop, under the BB routing is easy, but if he has braze on above the stay and wants to use it, the 626a, or comparable clip is the best answer.
BTW- I stopped recommending simply looping the wires below the BB without a clip, because it was too declasse for many on this forum, and folks would worry about the wire sawing through the paint (that takes 5-10 years, or more).
