Bulk edit of scheduled jobs

Does anyone know of a way of performing a bulk edit of scheduled jobs?

We have over 90 jobs which were created with a server name in the file path and that server name is about to change so each job will need to be edited

There is the SCHTASKS command and I know that you can create scripts to perform bulk operations but it doesn't appear to let you change the specifics of the job:

SCHTASKS /Change [/S system [/U username [/P password]]] {[/RU runasuser]
[/RP runaspassword] [/TR taskrun]} /TN taskname
