While you cant put stone boulders into bins you can use a slightly exploity method to store as many stones as you want on a single tile. Often refered to as a quantum stockpile there are two ways to go about it. The quick and dirty way is to set a garbage dump zone ( i, set a 1 tile zone, then hit g with that zone selected) then mark all the stones you want to move for dumping. The dwarves will haul all those stones to that tile. You will need to unforbid the stones after they arrive if you want to use them.
There is also an automatic way to acomplish the same thing useing minecarts. First you want to build a track stop next to the tile you want your quantum stockpile. While designating the construction you'll have a few options, one of them is to hit D to change the dumping direction, for this example tell it to dump north. Set a stone stockpile to the north of the stop(1 tile is enough) and 1 or more stone stockpiles anywhere else near the track stop. press h to bring up the hauling menu press r to make a new rout and with the cursor over the stop press s to define the stop. Assign a minecart to the stop with V. select the stop from the hauling menu and press enter. hit X a few times to clear departure conditions out. Hit enter agian and select the desired items (identical to a stockpile configuration). Once set escape back out and put the main cursor over one of your stockpiles and press S to make a link to that stockpile, T will toggle weather the stop is giveing or takeing from the stockpile. Link up whatever stockpiles to the stop (make sure its set to give not take from the quantum stockpile where its dumping too) Escape out the rest of the way and your all done. your dwarves will haul stone to the feeder stockpile(s) load the stone from the feeder piles into the minecart, and the minecart will auto dump the stone into the 1 tile quantum stockpile.
