Multiple Slack channel associations?

Hi anyone found a method, work around or 3rd party tool that allows multiple companies to be associated to same Slack Channel?
Our use case is a corporate hierarchy where we manage partner offices as distiinct conpanies with parent / child relationships. But want consolidated activeity for our leadership to funnel into same channel

Hi @PFogelsanger ,
