Custom liability for child support, garnishment and/or loan repayment

I have just started working for a company, I'm not sure which version of QBs we use. The company enters child support, garnishment and/or loan repayments deductions from an employee's check manually each week. We create the paychecks and then go into the individual's check and add additional deductions in the other deductions section prior to printing the checks. I believe an article recommends creating scheduled deduction. If this is true, how do you print the individual checks to the agency requesting the funds with the appropriate memo for each employee. Checks are currently being generated for each employee although all of the payments are going to the same agency. I.E. 3 employees have wages garnished for child support, Two employees support 1 child each; the third employee supports two children. Currently, we go into the check and edit the memo field with the appropriate case numbers and print one check per employee. Other articles seem to imply one check is written for all of the child support payments. Please confirm and/or correct me and explain the best way to handle these deductions.
