How do I add some utility applications to a Tumbleweed Live DVD?

Suse Studio will let me add the utility repo to a build but it tells me it can’t find some of the utility apps I want to add.
(Plus, Suse Studio did not have Tumbleweed as a base to build on that I could find.)

Is there a way I can remaster the Tumbleweed KDE Live DVD iso to add some utility programs?

Is there a way to use a live DVD persistent feature to install an application rpm?

Other?

My goal is to take the Tumbleweed live DVD with added utilities and burn it to a live USB for transportability.

Thanks for thinking on this!

Use kiwi and the image files, or OBS to create your image…
