Able to use the  text functions and the below value returns the first value in the list: 

 {{issue.AssetsCustomFieldName.AttributeName.get(0)}}
OR {{object.AttributeName.get(0)}}

In summary, the Assets smart value can be added to a variable and in this case, using the split function to create a list from that data will allow for list functions to work.
