I'm not sure which direction of "many" you are looking for. If you
want to test if multiple positions are in any exon, you can make your
`gr` GRanges object bigger (include those positions), and tease apart
your findOverlaps results by which subjectHits are overlapping with
which queryHits ...

Is that what you're asking?
