How to Create Plain Subprocess?

 Hello, I am new to both Bonita and BPM and am exploring their capabilities for our company's use. 

My problem: 

In the Bonita Modeller, I see only "Event Subprocess" available, while other modelers I have tested have just a plain "subprocess" option. A plain subprocess better suits my needs, because I would like to flow messaging tasks from Aubprocess A to Subprocess B (this appears to be imossible in an event subprocess - no flow going in or out). 

My question: 

How does one create a plain subprocess in Bonita? If there is an alternate way of solving my problem, I'm all ears. 

Best,

Jeff

Hi, for now BPMN Subprocesses are not supported, however you can easily reproduce their behavior using Call Activities and data mapping.

Regards.

Edit: I want to add the following:  

I just now stumbled upon Call Activities. Might they be what I'm looking for? 

Thanks,

Jeff

Is there an eta for the implementation?
