Wish list: trim along suppose to be fillet edges

For fillets, when tools like FilletEdge fails,
it would be nice if there was a tool to
Select edges to where you want to make fillet
then, if Fillet fails for some reason at least trim off
the adjacent surfaces of the selected edges.

So next action is to do sweep2 or blend srf.

It would be also nice if fillet tries and cuts off the filleted surface up to the where the failure begins.

I think I either do like pipe on edge and then extend to trim to continue with sweeps or dupedge the offset on surface to trim off first.

Maybe sort of trim from edges command…but
adding a arc tangent to surfaces…
