Hey Morry,
That is something that I have planned to add once development of the android app ramps back up (hopefully very soon!). Your changes would remain local though, they wouldn't update the site.
Also, if you do update your local course, you don't have to re-enter the round. Just choose to edit it on the site, choose a different tee (or blank tee) and then choose the one you played again and all the pars and distances will update to whatever is current.
