Number range assignment in KONV

We have a requirement to reset/create new number range in KONV for sales documents.  Our original number range assignment is as follows:

NO.        FROM NUMBER     TO NUMBER     CURRENT NUMBER    

01          0000000001               0999999999     197101    

02          1000000000               1999999999     1000014540

I have determined that range 01 is used for SD documents and 02 is used for MM

We have exhausted the entire number range for 01 and would like to create new range using SNRO

03          2000000000          2999999999

but I cannot find where to assign this number range to the SD documents (sales order and billing document)

Any advice is appreciated
