Samsung TV app - navigation possibility to go 10s back/forward

Hi,

WHERE: Viki app on Samsung Frame TV

WHAT: have the possibility to move 10s back (or 10s forward) in the show

WHY: I can finish reading a long subtitle (or skip the intro).

Existing workaround: Currently I need to watch with my phone nearby to be able to rewatch the last 10s of the show and pause to finish reading the long subtitle. To navigate elsewhere in the episode to watch on TV, I need to exit Viki app, get to desired place on phone, wait at least 1 minute, start app again. This works in 90% of the cases. Sometimes the delay needs to be longer.
