Support for Keyword Menus, Hierarchy, and Importing

Just wondering if we can get support for importing and exporting hierarchical keyword lists and putting them in a menu to use for selecting the proper key words for a file or group of files. Like most I use several pieces of software an having a way to make sure the key words added are identical and hierarchical between software and machines is very important.

Have to admit I can do this between Bridge and Lightroom and Bridge has the additional feature of "Import and Clear". Since its not a catalog this is really nice and allows me to update my list in Lightroom, export and Import and clear in Bridge.
It would be nice if Capture One could do the same in Sessions Mode.

Right now I'm using Bridge as a front end to Capture One (silly I know) just to let me insert Keywords and then work in Capture One. Also since I use both a Desktop and Laptop like most people It really helps to be able to import a list into a tools that has been developed on my desktop. I update the list, write it to dropbox and then do an Import and Clear on my laptop.

Just a request.
