Unified system for MBA Admissions

I was just wondering why can't we have a unified system for MBA Admissions in the US. Every university has its own application, own set of similar essays, we need to send GMAT/TOEFL scores multiple times, arrange transcripts to be sent to each school and so on....the question is - Do we actually need it? Why can't we have a common system where a prospective candidate just needs to send one set of GMAT scores, one set of transcripts and so on?

There can be a common body just like GMAC or ETS which would handle everything. There can be common set of essays (Goals, Leadership, Failures, Ethical Dilemmas, Personal History, Extra Curriculars etc.). Agreed, the WHY XYZ MBA question would need to be drafted for each school the applicant intends to apply - but that should be fairly easy for the applicant - at least all his other essays would be common. So here is how it can work -
1. Applicant registers on the unified website and creates an account.
2. He is shown a screen where he can select the schools he intends to apply. For each school, appropriate fee would be applied.
3. Next, he writes the common essays for all schools and provides the background information like Family Information, Employment information etc. Again, this is common for all schools --> just imagine the amount of effort saved.
4. The applicant can then write the customized essay(s) for each school like the Why XYZ.
5. Two recommendations are submitted, again the same recommendations can be used by all the schools.
6. Once, this is done, this unified body can generate separate pdfs for each scool - complete with all background information, essays (including the customized essays) and recommendations and forward this document (either electronically or paper based) to each school the applicant had checked in Step 2.

I think it just needs a little initiative and will of the schools and can save a lot of trouble for the applicants.
