Masks from multchannel EXR

Software Natron
1

Hi

When using Nuke to comp and using a rendered multichannel EXR the masks are embeded as channels, I could select a channel and use either RG or B from that channel as a mask on any node without the need to shuffle out and back in to the mask input of said node.
This doesn’t work with Natron

Am I missing something?
