Hi jj -
I might be misunderstanding you but I am going to run with what I think you are saying and see if it answers your question...
From what I gather, you would like to have the title on the template part of your listing be something that you choose and not just a repeat of the eBay listing title. If this is the case, right next to where you choose the template on the lister page, you have an option for "Template Title".
First, choose a template and then write your chosen title in that "Template Title" box. Your listing will then have the normal eBay title at the top of the listing and your chosen title on the template for the listing. (You will not need to "remove" anything - we will see that you have a template title you want to use and will subsititute it for the listing title on the template.)
Hope this answers your question. If I hopelessly misunderstood, give me a little more info and I will take another crack at it.
Thanks!
