Migrate code from R2011a to R2015b - Legacy flag for Set functions

I'm migrating existing Matlab code that used to run in R2011a to a newer version R2015b. There's a situation with the Set functions intersect, ismember, setdiff, setxor, union, and unique. According to the Matlab release notes these functions changed their behavior in R2012a and in order to maintain their legacy behavior I need to add a legacy flag to the function call (e.g. ismember(a,b,'legacy'). My existing code has thousands of calls to the Set functions so doing this manually is starting to look as a very difficult task to do and very prompt to human error.
Did Mathworks create some kind of tool to support users migrate old code but maintain their legacy behavior? In other works, is there an automated way, supported by Mathworks, to attach this legacy flag to the set functions?

To anyone else looking for a solution to this, Mathworks has a tool to support the migration of old calls to Set functions, the tool locates the calls to Set functions within .m files and lets you define if you want to add a "legacy" or a "R2012a" flag to the call. The tool is executed through the function legacysetfuns.m, just ask for it to the technical support team.

Hi John Well lucky for me Mathwork did create a tool for this which was sent to me after I created a technical support ticket.
To anyone else looking for this tool, it is a Matlab function called legacysetfuns.m, just ask for it to the technical support team.
