Follow-up triggers after custom campaign action

Hello,
We are using SAP Marketing 1809. After new channel implementation we have found that we could not use follow up triggers for such action (for example sales order). The difference is noticeable at the screenshot below:

So my question is - where could we change it? Should it be ABAP coding in custom channel class or just some parameter in Customizing Settings (SPRO)?

Thanks in advance!
