Pulling different end temp samples from one batch?

wondering if any one here is pulling roast samples from one batch, would love to be able to do one roast with some new beans and just pull out samples at different end temps, the tryer seems far to small to get enough to cup, and by the time you get what ever the weight of beans you need for cupping the roast temp would have risen to much? Iā€™m getting les than 2g each time, would be cool to have a extra long tryer or some thing :sweat_smile:
