different custom text in each navigation page collection header

[kostamilonakos]

hi I need help if anyone knows how to do custom writting for each navigation page collection header. My issue is I can name the navigation what I want to show to the consumer and thought I could do the same for the collections but it wont work and only displays the full name I have called the collection so i can easily differentiate from the titles when adding products. I want to use manual collections and not automated so have run into trouble as a result. See snips below of the issue, I would just like to be able to manual alter where it says ''Nintendo 1st level'' to say ''Nintendo'' for the customer without changing the heading name of my collection itself where this data is pulled from.  First picture is what I have had to do for now and not show anything and second picture is what I would like it to be but to be able to custom name the heading for each page without affecting the collection name. Thanks!
