Hi all, we've been looking into this and we have a partial solution with more to come. We recently added a new logical operator called "matches" (https://circleci.com/docs/2.0/configuration-reference/#using-when-in-workflows) that returns true/false if a value (say the pipeline value for the branch or tag) matches a given regex. Since this will all be in a "when", you can combine tag/branch filters in any way you want using AND/OR. The reason this is a partial solution is that we only have this available in places where you can use a "when", which covers workflows/steps within a job, but does not cover jobs within a workflow. However, we are looking into a "when" that can be used for jobs within a workflow.
