You could always "bag" some of the seedheads for long enough to ripen the seeds.
That's easy if you buy some organza bags. Craft stores may have tiny organza bags in the "weddings" isle. They breath and can be re-used. I think dark green is least obtrusive in the garden, but you can get white, red, or almost any color.
But this place has ALL sizes of organza bags, including some big enough to hold a bottle of wine. One of those will "bag" an entire stem. And their prices are good and you can buy a small quantity at the low price:
