while replacing templates to multiple hosts having multiple templates using mass update replace template option, having an option to map replacing particular template with a template and leave some of them which are not meant to be replaced will be a lot more useful as existing one replaces all hosts with the template selected and it is difficult to replace for multiple hosts having multiple templates. For example we need to replace windows agent template with all hosts having different templates like MSSQL, Apache, etc windows agent template is replaced and all other templates are removed as of now.
