We definitely do! ProWorkflow has a few inbuilt methods, like which manager is handling a group of jobs/projects, which priority every job/project has, and which customized category each job/project has.
We've also got other options. Custom tagging, in which you can create and apply several custom identifiers and report on that identifier as a grouping. As well as that, our numbering system can be fixed or variable, so you can include prefixes/suffixes and report on those as groupings.
Due to how customizable many of these options are, we'll be able to group your projects in whatever manner suits you best!
