Trying to find a way to make subset selection more user friendly. First thing first there are a lot of manually created subsets in this dimension, and as well as TI generated subsets. Users are ought to only select the TI generated ones, on top of that for each PAW book tab, they ought to only pick from a few.
for instance, I have 10 subsets created from TI, there are two tabs in PAW containing the same cube view except user is able to pick subset from one dimension. First tab, they should only see / select from 5 subsets and the other tab show show only the remaining 5 subsets.
P.s. I would love to hide the overview of the cube view if possible because:
1. I don't really want the user to mess up the element selection
2. I don't want to reveal other manually created subsets since they are not meant for selection
3. Its not looking good

Thought of creating another cube to allow user pick subset from picklist which then automates the selection of subset in the original cube view.

1. Enhance the TI that generates the subset so that it would also create elements into a new dimension using the subset name
2. In this new dimension, manually create dynamic subsets that group the elements by pattern. From the example above of two PAW tabs, there will be 2 dynamic subsets created with 5 elements each.
3. Create a mapping cube with two dimensions. One dimension with element representing the PAW tab, while the other is a measure dimension with picklist attribute referencing the dynamic subset created from step 2
========================================
\\\\\\\\\\\\| Value |
----------------------------------------------------------
Picklist 1 | <subset picklist 1> |
----------------------------------------------------------
Picklist 2 | <subset picklist 2> |
=========================================
4. Put this cube view side by side to the original cube view in both PAW tabs, 1st tab will show only Picklist 1 element, while 2nd tab shows only Picklist 2 element
5. In the original cube view, the dimension which subset should be auto selected should have mdx statement like follows: TM1SubsetToSet([dim],[cube].[measure].currentmember)
6. When user select a subset from the controlled subset list in the mapping cube, it will filter the original cube view.

Sorry having to write down the steps and editing a few times makes me doubt whether it will work

Begging for comments and ideas. Or is there a way already (like control cubes or function in PAW) that can do this.
Thank you in advance
