allow to configure attribution method for pages report

[#1]

Would be great if I could change the default attribution method for the pages report from linear to recent.

Many users dragging conversion events into the pages report and wonder about the strange data. This would make life much easier for site that don't report revenue and need that linear attribution

[#2]

I agree that this report should have the option to change between most recent, linear and Values set on the same page view Metric Allocations.

If not, I would recommend that the allocation metric is clearly stated on all reports so that users don't miss interpret the data.
