Script Render (bounce in place) 1x Offline ?

[Gaett]

Hello there,

Is there a way to choose the speed when rendering track (bounce in place). See picture in attachment please.
By default tracks are rendered at full speed offline. It seems there is no script either. And I really would like to render at 1x Offline speed

I mean this option can be selected when rendering a mix. I am pretty sure there is something somewhere.

Thanks for your help
