Unable to use dynamic variables in transfer_call Sip headers

I’m integrating the transfer_call tool in an automated flow and need to include dynamic variables in the headers (for example id_registro, id_campania, etc.) to pass context to the receiving agent.

The issue is that the system only allows static values, and I haven’t found a way to inject variables dynamically from the flow (e.g. {{input.id_registro}} or {{context.variable}}).

Is there any way or workaround to make headers dynamic within the transfer_call call?
If not currently supported, would you recommend an alternative approach (for instance, passing data via sipUri parameters or metadata)?
