Assigning Fixlet/Task to a custom site

I’ve created a fixlet under my operator site, it worked very well on test servers and now intending to move them to a custom site. Can anyone suggest a best way to do it? I’ve tried edit the current fixlet option to chose site from drag down is greyed out, for now I’ve created a custom copy of this fixlet and chosen the desired custom site where I wished this fixlet to reside and remove the earlier one which was created in my operator site but not sure if that is a best practice. Any suggestions would be of great help.

That’s the process that I’m using, at least for individual fixlets.

If you need to do more than one or two at a time, you can select multiple fixlets/tasks from your Operator site, use “File->Export” from the console menu, and export multiple fixlets/tasks to a single file. Then you can File->Import, select your exported file, and import the multiple Fixlets/Tasks into a Custom Site.
