Making a component with a number at the end of it’s name unique causes the number to be removed.
Example: I have a several components named <6x8>
If I make one of them unique it will get renamed <6x#1>
Expected name should be <6x8 #1>

I would love it that it can use a kind of template or expandable tag/short, Like ‘SLS105’ to ‘SLS-38x105 #001’
