Kind of spread as node I think you’ll find the solution.
This node lets you, starting form any value, to retrieve a spread of values with a regular interval (0 0.04 0.08 0.12 …) of any spreadcount, and all pins are spreadable. @velcrome made a really good work here.
Though this can be obtained with a linearspread, it behaves in a slightly different way. In your case it would let you to simply add a new slice without having to set any other pin. Linearspread, instead, would make you to adjust not only SpreadCount but also Width and Input (and Alignment though just one time).
I would suggest it to be included in the next release, as it performs a useful and solid operation.
