How to backup and copy Other > Custom Commands to another system?

I know I can easily backup and restore Virtualmin configuration, but struggling to backup one of Webmin module’s configuration. Namely, I’ve composed good list of Custom Commands in Webmin > Others section and would like to have them copied over to another system. How can I do that?

Unfortunately, Webmin > Backup Configuration Files doesn’t list Custom Commands module in the list of modules which are possible to backup :frowning:
