It should be possible to inject some Context variables when calling operation "Run Chain"

The Run Chain operation should have an optional parameter enables to define various context variables that would be injected in the context of the called chain. another attribute shoud enable to list the name of the outjected ones (ie put in the context of the parent chain).

exemple:

injected variable:
manager_name=@

project_type= research

outjected variable:
project_result
manager_name
