How to move requirements to another folder automatically ?

Hi all,

I have 3 folder in requirements module. One of them has the all requirements within. Every each requirements has a field which keeps information about folder that the requirement will be moved. I would like to move all the requirement to related folder automatically. 

For example;

Folder A -> 50 requirements

Folder B -> 0 requirement

Folder C -> 0 requirement

In Folder A, 20 requirements should be moved to Folder B, 30 requirements should be moved to Folder C. It will be specified by the special requirement field which should moved to which folder.

It can be SQL Procedure or action does not matter.

Thanks in advance.
