Solidworks Predefined Dimensioning

Hi all

I wanted to know if I can make a list of predefined dimensions on solidworks.

For example, I represented a tank in DN50, I put an equation to modify its diameter, but the problem is that I can modify it freely and therefore enter diameters that do not exist. 

However, I would first like to make a list with all the DNs (Normalized Diameter), so that when changing the diameter I only have access to this list of values.

Thank you in advance.

A good family of Excel parts and you generate all the DN possibilities of your tank (and as your dimensions are controlled by Excel, you can set SW so that you can't modify them from the 3D)

Perfect, thank you very much for your help!
