Please add a system variable to change the default setting for SLINE ("new sline group" vs "continue sline group"). When drawing a new sline from an existing sline, the default is to "continue the sline group". To create a new group, you must type "n" and then press the enter key before routing your branch line. For our firm, 99/100 slines should use "New sline group", but many people forget to type "n", so having the option to change the default would be extremely helpful.
