Update Softaculous Installation List

Hello. I migrated a WordPress installation to my Business Pro plan successfully. Of course, since it wasn't installed via Softaculous, it isn't in the list of installations. I've corrected this before with other hosts but can't recall how it is accomplished. Is there a method? This would allow me to use Softaculous to create a backup or clone the site, which are nice features to use prior to significant upgrades. Thanks for your help.
