Possible to name ISO files in Dreamshell's GUI?

[Turbokat]

Is this possible to do using the controller? I currently lack a keyboard, I do not have the Dreamcast broadband adapter. The way I dump ISO's is via HDD PATA enclosure. However I get weary connecting/disconnecting that thing to dump DC games.

Recently I made a small error, I added a bunch of covers to ISO files and GDI files. The problem is with GDI files I renamed the folders to match the GDI FOLDER and not the GDI itself (silly me, I got a bunch of GDI's that say disk/optimized_gdi and not the name of the game). Is there a way I can rename them in DS menu or will I have to reconnect the enclosure again and rename them on my computer until I can buy a broadband adapter?
