Reverse Search using edgeGram in autocomplete searches

For searching on the last few characters of a field's values, currently the only option available is to create a nGram or need to create a custom analyzer with regex split/capture group. As lucene internally has the reverse option available, can we have reverse flag provided with edgeGram to perform searches from the end? Use case: Lets suppose the field is tokenNumber and we usually search by the last 5 digits of the tokenNumber itself.
