Bigger area for metadata comments?

I would like to create a bigger more robust area for entering metadata comments. I think I will be able to do it via a script dialog. However, I thought I should ask if Opus already has a way to do this. I would like something like the box that opens for the new folder dialog. Are there any commands that open a bigger area to type in the metadata comments? Thanks

One of Auden's scripts may be what you're looking for:

Wow, I knew I should ask first... this super. Thank you Auden and Leo!
