I've never heard of such a feature... that would be cool to have... as such, I tend to make my text and titles more generic so that they aren't "hard-coded" to a specific year... I use terminology like "this year", "last year", "previous year" (this one if I am looking at last year compared to the year previous to it), "last x months", "last x weeks", "last x days", etc.
Basically, because I know the reports are going to roll over time, I try to avoid locking the text elements of the report that will make them stale dated very quickly.
I know this doesn't help you find the reports where this is already in place, but it might help inspire you to think of alternate text inclusions.
The other option, if you need to have specific years and date text in your reports, tag the entire report with a tag like "hard-coded text requires updates" (and if you have stuff that requires yearly updates and monthly updates, you could add secondary tags of "monthly update required" and "yearly update required")
So that next time you have to update your reports, you can filter for the tags above to find the ones that need updating.
This of course relies on ensuring that all such reports are properly tagged, and that can take a while to get onto, but without a find and replace in reports feature, there's not a lot of options.. at least try to prevent some of the headaches next year.
