If your pipelines are just straight through linear triggers like A -> B ->
C you might want to consider whether A, B, C need to be different
*pipelines*, or could just be *stages* within a single pipeline.

Otherwise the number of pipelines shouldn't be a concern unless you have
thousands. I'm not sure what "comfixed" means, but if it's just the
dashboard view that is confusing, consider grouping pipelines and/or
applying permissions to restrict how many pipelines people see. Or have
users set up dashboard filters to see only the ones that are relevant to
them.
