prevent reindexing for specific doc?

[UR user]

Suppose I store a large word or pdf document into a UR database. Suppose also that as I read the document, I highlight. When I save that highlighting, UR will reindex the document. If that document is 1000 pages long, it will take a long time--even though no text has been added or deleted.

Is there any way to toggle auto reindexing for embedded documents? I'd love to be able to shut reindexing off on a few large docs, so that I can highlight without dealing with the long reindexing lag.

Thanks.
