Contant values - selector mode

[arch3d]

Hello,
I got three constant values eg. 10cm, 20cm, 30cm and i would like to use this numbers only to define padding start/end of 1S1. Is it possible to create something similar to selector with index parameter?
eg.
- If I select 1 padding start/end will be 10cm
- If I select 2 padding start/end will be 20cm
- If I select 3 padding start/end will be 30cm

Thanks for help
Michal

PS. I dont want to use empty segment at start/end of generator or nest generators

Here is Macro for that.
Connect your Constants to Input1-input10 and your Selector Numeric to Index Input.
