Edge 'offset' ?

[Selur]

This might be a 'strange' request.
I got this:

and I want to remove the lines that are not on the edge,

(between the pink lines; sorry, not the same frame, but the lines are static, so it should still show which lines I want to fix.)
using clip = core.edgefixer.Continuity(clip=clip,left=50) this works:

but since left=50 seem rather large, I was wondering it you could add the possibility to add something like an 'edge offset', once could apply the filter to a region that is not the edge. ;)
