I have about 250 markers with tiling on.

Everything is working fine. When you zoom out only the 100 "Tacks" are shown and the remaining 150 markers are just dots. Which is just fine.

My question is, is there anyway to change which 100 (or whatever you have selected to be shown) show the tacks instead of the dots? Currently it looks like it's based on how I entered the data - which could be by date or alphabetically. When my map is zoomed out the 100 of the 250 that show tacks are all clustered together. I'd rather have the markers showing tacks to be spread out across the map instead of in one big clump. Was hoping there might be a way to do this.

Thanks.
