Great question, we hear it quite often. Currently there's no great way to solve this problem, but we are working on a feature that will allow to combine pipelines and add their ingest functionality onto another one.
This way it's going to be possible to combine functionality that comes Out-of-the-box by Dynatrace with custom processors and it's possible to create global (or widely applicable) pipelines (e.g. for global bucket and security context assignment; or for common technology parsing that is identical across many pipelines) and combine those. In combination with our upcoming fine-grained permissions this will also allow for access and edit control of stages, so that e.g. teams cannot interfere with a global bucket assignment scheme.
