Different Priority/Frequency for Pages using the same template

Hi,

Is there any way I could achieve this?
The point is that I have more static pages.
Most of them belongs to the same section and are using the same templates.
I would like to give this group a higher priority / update frequency but leave the 60% / Weekly setting for other static pages.
Any way to achive that?

I am using plugin’s latest version (3.2.9) + WordPress latest version (3.6).

Thanks in advance!
