Content (please ensure you mask any confidential information):

As per the explained functionality, my maintenance work and Supervision are enahanced to deal with the work execution part. However, it is not clear if it is still possible to use the functionality without using My maintenance work, i.e using Dispatch list. Or, is it possible to enable the feature and use it for organizations using dispatch list as well as my maintenance work in the same instance? In out case, only few sites are enabled for my maintenance work while others still use dispatch list. So I want to be sure.
