Combining And Rearranging Data Records From Multiple Worksheets To A Single Worksheet

I have a set of related variables that are split over multiple worksheets, and I need to be able to take specific information, duplicate certain values and produce an output sheet for use in a separate piece of software.

The variables are:
Position Number (Sheet 1)
Position Title (Sheets 1 and 2)
Position Requirement (Sheet 2)
Requirement Importance (Sheet 2)

The output sheet requires a list of all the requirements for each position number, which means the position number itself needs duplicating (in new rows) X number of times, where X is the number of requirements assigned. The appropriate requirements are then to be pasted in next to each position number (and the requirements can be found by comparing position number to title, and from title to requirements).

Normally, I’d be able to do this using lookups and so forth, but my problem arises when I have multiple position numbers with the same related title (in the attached example, there are three plumbers with unique position numbers). I can’t figure out how to say to Excel “a plumber has five requirements, and there are three plumbers, so duplicate each position number for each plumber five times, then insert the appropriate qualifications (and their associated importance values) next to the position numbers”.
