Analysis for Excel: filter component has lower functionality then usual filter

Hi,

I have a question about filter components in Analysis for Excel.

When I use filtering from navigation panel, there is a lot of useful things in filter dialog, such as search by part of name, selecting intervals and so on.

But when I make a filter component in the free area of my workbook, it has much lower functionality: no search, no intervals, only direct list of dimension values.

Is it a bug or a feature?

This filter component looks like inconvenient in case of more than 20 values in dimension.

Is there any way to make it "fully-functional"?

Versions: Analysis 2.2, BW 7.5, Excel 2010.

Thanks.
