Time Stretching and Frame Range QoL button

I think there should be a checkbox called "Apply Time Stretching Values to Output Frames"

Because right now, after entering a non 1:1 time stretching value (old 60: new 24). I need to look at my Frame Start/End values. I need to pull up a calculator and multiply by .4 and then enter that new value in the Frame Start/End fields.

This makes using Time Stretching a clunky process imo. Why am I needing to manually remap the Frame Start and End times? The ratio data is right there. Why can't it be applied to the Start/End frames automatically. Is it because of fractions? Is frame rounding bad?

The proposed checkbox would have it so, for eg; with a 60:24 time stretching ratio, I have an animation Frame Start set to 8000, the output frame that Blender would render, will actually be frame 3200, labeled as 3200.

This would be a QOL addition to time stretching to make it easier to use. I would also allow the change to be backwards compatible and optional if this doesn't fit in someones workflow.
