An easy way of 'retiring' numbers is to Edit the preset, and adjusting the values accordingly.
For example, if the preset is from 0-10, you can adjust the slider so that it's now 1-10, or 1-11.
If you are using Custom presets, then you can edit the preset and delete items from the list and add to the list. (Save a copy of the preset first by going to SETTINGS and pressing SAVE AS).
And I just answered your translation question in the other thread.
Hope that helps!
