Can one workflow call another workflow without creating child workflow

Hi Antonio,
I am already using activities from my current workflow. I was having a scenario where say I already have 5 activities which I have spawned from one workflow. But the business usecase was that I have say 50-60 organisations and I need to use those same 5 activities for all orgs since functionally all orgs want the same code that’s written in those 5 activities. However currently I have a master workflow say workflow1 inside which I have loop for those 50-60 orgs and for each org I want to call the same 5 activities. These 5 activities are not currently in the master workflow but in a org specific workflow say workflow2 and inside the loop of workflow1 I want to call workflow2 50-60 times.

I read below from @maxim the purpose of creating child workflows and hence posted this query
