yes, but you'll have to edit the XML file yourself as, apparently, it was too tricky to put that in the layout editor.
check out the standard autohide layout and mimic that format in whatever other layout you want to put it in, and you should be fine.
off the top of my head I think the tag is <autohide>
and nested inside that tag you can have a <section> tag with a side and activationarea(or something like that) properties
check in:
C:\Softimage\version\Application\layouts for the files and open it with a text editor, it's plain XML formatted text.
