chaining workflows - can one workflow trigger another?

i have a main workflow thats getting really long and complex (about 30 nodes). want to break it into smaller workflows that call each other like: main workflow handles the form submission and basic validation, then triggers a "process order" sub-workflow, then triggers a "send notifications" sub-workflow is there a way to call another workflow from within a workflow? or do i need to use a webhook as a bridge between them? also wondering if the sub-workflow gets the data from the parent workflow or do i need to pass it explicitly
