Missing checkbox "Use current frame" for setting thumbnails on task page

Context

Kitsu version: EmberLightVFX's Docker Compose / 0.20.30
Production type: Short

Describe the bug

It is not possible to set the thumbnail to the current frame of the video player from the task page. On the sidebar of the overview this is possible to do so with the checkbox "Use current frame" which is missing for the task page.

One more thought: I think setting the current frame should be the default behavior on the task page since you would generally open the larger preview to precisely select the frame. The new box could maybe be checked by default.
