New folder in Pool?

I want to add a new Pool folder so I can bounce Selection into this new folder. But I can only create a folder the “Select Pool Record Folder” is greyed out so my question how do you do this if I can’t select the folder?
Also how do you guys bounce multi mic(string quartet or drums) muliple takes starting different places. I used to use select tool and grab all lanes with Group edit on, and it would bounce all the different lanes. But now it just bounce one file. Whats the point with that I can do that if I do it on the audio file without the lanes open?

I don’t think creating subfolders in the Pool is possible. You should try using a naming convention to differentiate your files in a way you will remember.
