When an engineer creates a markup of a visualization inside of a Change Order, they sometimes need to exit the ECO in process, to look at other information somewhere within Vault... another drawing for example. So they save the Markup, save and exit the ECO without submitting it yet.... and go about whatever they needed to do. Then when they are ready, they go back into editing the change order. however, Vault will not allow them to re-open the Markup they had saved and continue editing.... it forces them to save their new changes, along with whatever markups they had already done, as a new markup file. There have been instances where I have gotten 5 markup dwf's containing essentially the same information, built on with each successive markup.
It would be preferable if they could simply reopen, add some markups and save the same dwf... so all markups end up in one file. The current method is cluttered, messy and begging for something to get missed.
