Ability to Lock Baseline To a Specific Date

Once a schedule is agreed to, that schedule is the "baseline"

Wrike needs the ability to lock the base-line date to avoid the user having to either remember or externally make note of the agreed baseline date.

Having the baseline move to current date within Analytics doesn't make any sense. Please add the ability to lock the baseline date, so each time Analytics is selected we can see how the current schedule is performing relative to the agreed baseline without having to remember or source what that date was.

Thanks!
