Is there a way to not have versions created for files in the vault? In WorkGroup they had a "Working Copy" function that was essentially an overwrite of what was currently in the vault. A similar function in EPDM would be nice for more early concept work where a lot of changes may be happening and racking up un-necessary versions. We could call our state "WIP". Is it possible for documents in "WIP" not to have more than one version created? The vault under "WIP" would act more like a network share then, rather than a versioning system. This would encourage users to work in the vault sooner rather than later.
The only way I can think of would be to setup two vaults, one for WIP and other for Production. Do your R&D in the WIP vault. When reaqy for production, move the files to the Production vault and then destroy all the versions in the WIP vault for files moved.
