Yet another update question

I know there are several of threads along these lines, so I apologize if this has already been covered elsewhere. I just submitted update letters to schools tonight to notify them that I will be presenting a poster at a national conference. I just now found out that another abstract I submitted was accepted for a poster at a different conference. Should I send an update about the second conference? I wasnt sure if it would make a difference since I just sent a similar information. However research experience is one of the areas my application was lacking in, so Im not sure how to procede.
