Sparse vector in imfilter kernel

What would it take to make ImageFiltering.imfilter work with sparse or “dilated” kernels? I know it supports OffsetArrays, for instance. We basically need to skip every few values so a filter like [-1,0,0,0,1] only performs two multiplications. I’m thinking it’s something that might already work out of the box, but I can’t find any examples and have little time to investigate now, wondering if someone familiar with the library would have any ideas.
