You can change title to the price list

My memory tells me I've never done it.  Short of opening the program and trying myself, I can't say for sure, but I would assume you can.  It's easy enough to test.  The first three Regular, Preferred and Web Price are not modifiable either within the program or database (though I haven't tested this in about 10 years).

...or add a new item to the list price in any version of Sage 50 CA ?

That is the default and only option.  Each item has each available price list possible.  You decide if a price list is applicable to the item and put in a price.
