have you tossed out dick's idea of a program?
if so, here's the system I created. You could too.
1. create JOB1 with a step for each date STEP01 to STEP31 (you decide which steps process what)
2. set up JOB2 with an IEBEDIT step and a control card to copy JOB1 to INTRDR including only a single step, STEPnn.
3. set up JOB3 running pgm=EZACFSM1 to read JOB2 and replace 'nn' in the control card with &LDAY and submit to INTRDR (see MVS Init and Tuning Reference for a list of symbols EZACFSM1 will resolve while copying JCL or data files).
4. submit JOB3 which tailors and submits JOB2 which tailors and submits JOB1 containing STEPnn for today's date.
A simple pgm would be less complicated and reusable elsewhere!
