Is there a way to hot reload a controller into Beego following a code change?

Is there any way to configure Beego 1.4.2 to hot patch a modified controller following a code change? Out of the box it reloads the entire application following a controller edit, thus causing any session data to be lost. A comment in GG suggests that hot reload existed in Beego 1.3, but I can't find any info as to why 1.4* does not do this. IMHO Beego is a neat framework but I wouldn't use it for a large project without the ability to dynamically update controllers.
