How to inherit an attachment from one process to another, more specifically from an initial process to a sub process?

[davidparraz41]

Context: I have an initial process that executes other sub processes. 
This first initial process I'm starting with the REST API with an attached document 
and I need it to be available in all other sub processes that continue. 

I have tried to use DeledateExecution from the Activiti API 
but I have not been able to add an attachment at runtime. 
Thanks for your help!
