Haven't found that option. Also, I was hoping these VBA variants would do the job. The first one is a broken download (Probably about to ask romhacking about it) and the second one does exactly what I want, but only with GBA even though it also runs GB.

EDIT: Well, that archive wasn't really broken, it will just open only with WinRAR and not 7-Zip.
