Any plans for a deflate_index_resume() function in /examples/zran.c ?

Recently I was 'playing' with huge files and (for my testing at least) I had to abort the indexing from time to time.
I was wondering if there is an appetite for a deflate_index_resume() function ?
I suppose I could get inspiration from deflate_index_read() to get the the indexing going again from a certain point onward, but I'd feel better if done by the author himself, maintained in zran.c
