Lock down the time line

If this is already possible, I apologize, but I couldn’t find a way.

It would be nice to be able to lock down the time line, so that it doesn’t jump back to the first frame when looping back to the beginning. When it jumps back, I have to scroll back to the end, just to start working again. To be a little more clear, I’m not talking about the playback, I want the animation to play all and loop normally, but I just want the option to keep the timeline from moving when the animation loops back to the beginning. I hope that makes sense.

Thank you! : )

You can right-click the play button and check that the “Rewind on Stop” option is unchecked:
