Single decklink producer to multiple channel

#1
HI
Can someone help me wit idea to solve my problem.
i have configuration that have 1 screen consumer, i would like to play decklink input to that consumer like
play 1-1 decklink 1 format 1080i5994 and also record it to file with add 1-1 file test.mov, but if i start something like play 1-2 pattern loop than recording test.mov have that pattern instead of layer with live video from decklink.

is it possible to play decklink device 1 to two different channels so i can record one channel and have live compositing on second.
