Cant render and replace audio clip with handlelength

Hello,

I cant figure out how to render and replace just audio clips WITH handlelength. For videoclips its working fine, you can just choose format and handlelength but the window is not popping up when doing the same for audio clips.

To put the problem in larger context. I work with 32 Bit float audio and want to export aaf to pro tools. 

When importing to PT, the audiofiles, although they were gainstaged in PP and dont distort there, they are distorted in PT but on a lower gain. When importing a before “rendered and replaced” clip, its ok in PT but I cant work without having any handlelength. 

Maybe someone has an idea?

Thank you!
