A very valuable tool to add to the Studio arsenal would be a platform for simultaneous signature. Signatures are a huge bottleneck in a project workflow, sometimes taking weeks to gather all necessary signatures due to "one-at-a-time" check in/check out requirements in Studio Project or even worse, routing via email etc.
If Bluebeam added a module or extension of a Studio Session or Project that allowed for simultaneous signing, this would be a huge benefit.
