Lock down of workflows, tasks & deployments

Please please please can I request that you implement a way of locking down user created workflows, tasks & deployments. It's something almost everyone I've spoken to who uses Episode wants (I work in post production), agrees with & can't understand why it's doesn't already exist unlike almost all other major encoding software. 

     Today I almost had a job completely screw up because a user (junior) had accidentally saved over a workflow after customising a setting. It's such a simple thing but would make a world of difference.

Thanks,

Leon
