Export to Disk node for a Render Target Cube

Trying to use the Export to Disk node for a Render Target Cube. It works for a 2D Render Target. Is there an alternative method for achieving the same goal; Exporting a cube map to file? There is the Export Render Target node but that only works for 2d Render Targets.

Did you ever figure this out?

Hey do you know where is save location?

Did anyone find out the save location?
