In my page template i have many url links. i want to allow users in EPiSevrer to change the url name or link when they wish to update link name or address. have a page template, for this i have a page type which has a property (LinkProp) of type 'URL to page/external address'. - So far I have...

<asp:HyperLink ID="myLink" Text="NewLink" runat="server"
            NavigateUrl="~/SearchTemplateNew.aspx">MYLINK
            <EPiServer:Property ID="Property1" PropertyName="LinkProp" runat="server" />
            </asp:HyperLink>

In EpiSever - users can add URL address on my page but i want them to be able to replace existing one. Can someone give me ideas how to achieve this? Many Thanks!
