I don't know such configuration.
All entries in search help for field "No. Columns" are maintained on domain level.
I tried to append my values with Fixed Values Append function - 10 and 30, but it didn't help me as the system always check only standard values of the domain and issue an error:
Enter a valid value
Message no. 00002
Procedure
Display the allowed values with F4 and correct your entry.
