How can I create multiple related lists from the same table?

[gjz]

I would like to have two cost plan related lists on Demand and Project - the current related list that OOTB and another one for the cost plans that are created from Resource Plans.  I would also like to have different verbiage on the tabs. Does anyone know how I can create two related lists from the same table and customize the name of one of the related lists?

I have created a custom relationship for it - but I can't add the filter to the custom relationship.

In order to have it function the same as the OOTB Cost Plan related list this is what I did:

1. Copied the existing relationship (System Relationships -> Cost Plans) and named the new one RP - Cost Plans.  The original has "Query with" code that needs to be retained for my related list.

2. Changed the original Related List Entity to include a filter to limit the results to the cost plans I want.

3. Added the new related list by navigating to Demand -> All -> selecting one -> Configure -> Related Lists.

4. When I go back to the Related list (System UI -> Related List -> Demand - Default view) I can't add a filter because the new one I created doesn't have any columns to select for a filter.  In fact, while it does show cost plans when I view the demand it doesn't seem to have anything I can modify.

5. I also tried it by adding another Related List Entity (cost_plan.task, which is how the original is created) and adding a different filter, but all it did was change the original filter to match the new Related List Entity.

Neither option works.
