How can we add additional user defined TYPE, OBJECT, METHOD in existing Default COLLECTION

Hello Experts
Is it possible to add additional user defined TYPE, OBJECT, METHOD in existing Default COLLECTION? If yes can u give me syntax or TDL Codes.

For Example:
I want to add some more Filters in the existing Default Collection Inventory Entries, I have tried as follows in Part Level but It is not working. can any one help me to achieve this.

Local : Collection : Inventory Entries : Filter : TestFilter


also I have tried as

Local : Collection : Inventory Entries : Add : Filter : TestFilter

[System:formula]
TestFilter : $abc = #xyz

for this you have to Define yours own collection..in that collection add your Filter..

 

Use switch option
In that option create n use yr own collection n apply filters
