With a bit of coding, you can use the GenomicFeatures package to get this info.

Build your TranscriptDb, then look at the help pages in ?transcriptsBy

If you store your query positions in a GRanges object, you can use the
results returned from the functions above with
findOverlaps/countOverlaps to find your hits.
