Ability to quickly retarget those who were missed/errored out in a journey

Description - Given AJO developers that ability to quickly retarget profiles that were either mistakenly missed / went to the wrong path / errored out due to human errors like wrong rules set in conditions or vice versa, exclude customers who received xyz notifications from AJO already. 

Why is this feature important to you - Human mistakes happen and teams often need to respond quickly to them. It would be super helpful to quickly identify those who were targeted, went to a specific path by mistake, or even exclude those who were targeted, so business can quickly recoup loss sales or communications.

How would you like the feature to work - Some sort of querying / ability to define rules for retargeting

Current Behaviour - It seems like building a segment and waiting 24 hours to be used is the only way, which often times marketing / leadership team is not happy with the wait time.
