Creating Business Configuration Activity List for a Custom Object

Hi Experts,

I have noticed the Fine Tuning elements of many Standard Business Objects .They contain many configurable objects like Number Range ,Usage Restriction,Involved Parties and others .In that list I want to add these two below activities to my custom object.

1.Maintain Number Ranges

2.Maintain Involved Parties

What is the best approach to get a similar screen and as well the functionality like standard.

Maintain Number Ranges

Maintain Involved Parties

Mainly I need to know how to structure my BCO to get a layout like the above standard screen.And also I want to understand how these dropdown fields are enabled for Involved Parties when I tried to add a new row.

Kindly share your valuable points on this requirement.Thanks in advance.
