SSAS Perspective Performance

Hi Experts ,

I need a Quick Advice .
I have a Cube (SSAS 2008 and SSAS 2012).I am working on 2 Projects .

I am creating PPS reports(In both the Projects) on the Top using Cube as a Source .
I have 10 Dashboard and Each Dashboard have 10 PPS Reports.Each PPS Report use Different Calculate Measure .(Around 100 Calculated Measures are used in all the Dashboard).

On the Drill Down of PPS Report I want to Limit the Dimension I see .

REQUIREMENT:: I have been asked to Limit the Dimension for Every Report (Every Report should see different  Dimensions on DRILL Down )

I have been asked to create Different Perspective for Every single PPS Report. That mean near to 100 Perspective in Single Cube .

Qusetion::
1) Is it a Right approach to create Seperate Perspective for Every Report(Around 80-100 Perspective in One Cube )??
2) Does it Affect the Performance of the Cube ?? IF Yes then How ??
