Double work zones

Content

Hi. 

I have this scenario: We have one technical resource with 2 different work zones, sometimes been created 2 work orders (activities) for each work zone, but in the same time interval, routing consider that this technician accomplish with this work zones and assigns these 2 work orders at the same techniciant and, with the same time interval.

I need that in those cases, routing does not assigns the 2 work orders, if an interval has been taken the another work order (with the same time interval) do not be assigned.

Regards.
