LTSCALE on spesific lines

[Siberian]

I have many lines that are dashed in different ways in my drawings. Is there a way to make the LTSCALE command affect only spesific lines? And if not, how may I solve it?

Before drawing the lines, set the Celtscale to a factor you want... or
To edit, click on the line and you can change the Ltscale in the Properties dialog box.
