Since we can't customize ECO routing (no the approval lists are NOT sufficient, they are just barely passable), it would be nice if we could get a route to reject back to work from review.
A lot of times we find minor updates during the review process, things that are "acceptable" to the engineering checker, but not acceptable down-stream.
Right now we have to reject the ECO, reopen the ECO, and re-submit to work. This takes 2 people (the rejecter and ECO admin) and 3 operations. We find it either gets delayed because the ECO admin has to get involved, who is usually busy doing his own work, or because the folder gets physically handed off without all the corrosponding electronic steps to get from a->b.
Please please please please please consider updating the ECO routing to make it as flexible and powerful (or more) as you have with the file/folder/project lifecycles. Being able to setup custom (dept.) routing and group level (instead of user) signoffs would get you 95% of the way to having a fantastic ECO system that we could build into a fully electronic 140001 capable tool.
