slashed circle for harmonium organ stops

[arnepe]

hello list,

has anybody written or transcribed music for harmonium (pump organ) ?
Circled numbers/letters show the organ stops, and slashed circles are used
when the organ stop is deactivated (example image from Rossini's Petite
messe solennelle").

So far I've used "nVier = \markup { {\circle 4 } }" (MWE attached) - is
there a way to create a slashed version of "\circle" ?

cheers and TIA
Arne
