Is your feature request related to a problem? Please describe.

In some cases (such as mobile connections) SPD entries can't be assigned to reqid's as these would overlap for new sessions. When using the new "Connections" option, we are able to trigger on connection events, in which case we can figure out which reqid is reserved for the current session

Describe the solution you like

Allow to select either a predefined reqid (current situation) or a link to a connection child.

Describe alternatives you considered
