Crystal Reports Pass over data from SUB REPORT to MAIN REPORT

Message

   Good Morning, I have a really painful reports that I am modifing and trying to add some subreports to it and for the life of me I can get it the way my boss wants it. 

The report main report and sub reports have no relation EXCEPT the JOB# itself.  
1. I would like to know if I could pass over the jobs #from all my subreports and embeded them in the main report and all the jobs are line up numerically. Is that even possible?

2. Then I need the main report to add up the subreport and created the sub total for each job number, and grand total at the very bottom of the report. Is that even possible? 

here is the main report and how its I got it to lay out right now

job#       Job Desc       materail      labour     overhead    Cont1 Cont  Cont3 
2222-4     Sales            500             100             50
1202 -2    Sales2          1000           200             300
3333 -1    Sales            750             150             300

sub report 1 
1202 -2                        (300)                                          300
5555-6                         (120)                                          200

Sub report 2
3333 - 7                        (90)                                                       90

sub report 3
1202 - 3                                         ( 120)          (20)                           140  

Here is how we wants it to look like 

job#       Job Desc       materail      labour     overhead    Cont1 Cont  Cont3 

1202 -2    Sales2          1000           200             300 

1202 -2                        (300)                                            300
1202 - 3                                         ( 120)          (20)                           140  

                     Subtotals   7000          80              280         300            140

                    Grand Totals   of all the amounts
