How to route co-relation to local event, if there is a global route also exists

Hello All, I am new to Camunda BPMN.

I have 3 (potentially more) processes where we do some type of calculation after process finishes.

So there is generic calculation and there is specific calculation, but event-sender process generates same-event (calc-event), now even if the BPMN has local catch event, the co-relation still goes to global-generic event, how can route it to local BPMN where it is defined?

When sending the message, you can specify whether start events should (or should not) be considered.

how/where do I specify that

MessageCorrelationBuilder (Camunda Platform Javadocs 7.15.3-ee) or MessageCorrelationBuilder (Camunda Platform Javadocs 7.15.3-ee) That’s all I know of.
