Filter Window - Adjustable?

Hi,

Is there any way to re-size/adjust the width of the FilterWindow?

When exploring multiple levels of a dimension, my business partners find it very inconvenient to have to use the horizontal scroll bar to see lower level members (see screenshots below). It would be easier if they could simply drag the right edge of the window to expand the width to a more accessible viewing window size. A larger window width would make the exploration experience more productive.

If this adjustable window feature is not available in BI4.0 SP8.3, is it available in a later version?

Thank you,
