Dumb Altium Question

[FotatoPotato]

Hey all,

So I just switched from 6 years of Eagle to Altium designer and it has been quite the experience so far... While I do like altium there are some things that just piss me off royally 

Anyway, I'm working on a power supply layout and I was wondering if anyone knows how to assign relief connections to specific polygons and specific parts but not others. If you look at the attached picture, I don't want any reliefs on the GND pad of the IC but I do want them on all of the MISC components around it. I also don't want reliefs on the big connection coming in from the right corner. Lastly I did set my clearance to 50mil on all polygons the Design Rules but it seems to have changed nothing and as you can see the distance between the two planes is really small.

Thanks for the help
