Create same entry onto numerous records on a portal via a search
I have a contact database in which I when I look through a contacts record I have a "Communication" portal that will tell me what contact I've made (Date, type[list], Notes).
Sometimes I do a search with a certain criteria (ie what type of contact they are or area, etc) and then do a mailout or mass communication to these people (could easily about 900 people).
What I would like to know is how to create a new entry into each of their "Communication" portal entry detailing the date, type of communication and notes so that all 900 have the same entry.
Currently I'm doing the crazy thing of going record one by one and creating this entry all 900 of them into their corresponding records....
I know it's most probably a simple scrip or something like that but am at a bit of a loss on how to go about it.
