Is there an escalator-free Tube map for dogs or assistance dogs?

Morning all,

Bit of a random one – does anyone know if a Tube map for dogs / assistance dogs already exists?

I mean something like a map showing escalator-free stations specifically.

I know there’s already the step-free map, but that’s more aimed at wheelchair users and shows lifts / full step-free access, it doesn’t really help if you just want to avoid escalators.

From what I’ve seen, there isn’t a clear way to find this info anywhere. So I was wondering if anyone’s ever actually made something like this?

If not, I’m tempted to try putting one together (going through stations one by one etc), would anyone actually find that useful?
