Automating Attributes

[Adam Long]

Hello! I apologize if this question has been asked before. 

Awhile ago, we've listed our devices with specialty software. We made an attribute slot for each applicable software that was installed on one's laptop. I'll attach a picture to make better sense of it. However, shortly after, Jira must've updated, because now we can put several software objects in one Attribute slot. 

And going forward, I apologize if I'm not labeling everything correctly. As you can guess, I'm extremely new to figuring this stuff out. 

So, as an example, I've set up a test Schema called "Assets Test"
In it is a schema tree for "Laptops" and "Software" software includes basic objects such as "email" "call" "cad" and under laptops we have "bill laptop" with attributes of "All Software" "Software 1" and "Software 2" There are objects in "Software 1" and "Software 2" however we want to automatically move all existing objects in the slots to "All Software". Making sure to not delete anything from Software 1 & 2 just in case something goes wrong. Again, I'll attach pictures so it makes more sense.

I'm having a lot of trouble working on the Automation Rule. I've come across this post here:
https://community.atlassian.com/forums/Jira-Service-Management/Add-multiple-objects-to-Object-field-using-Edit-Object/qaq-p/3121565
However, me being new, I'm having a hard time making sense of it all.

Any help at all would be GREATLY appreciated. Outside of the test schema there are several laptops and desktops that need stuff moved and going through and manually moving them will take forever.

If there is any further information I can provide that will help with this. Don't hesitate to let me know.
This is also done on the browser version of Jira. I believe with cloud service?
Thank you!
