Hi there! I have a list with over 11K emails from a user panel recruiting spreadsheet. I have a list of 300 emails that are spread all throughout this list that I need to find. [scenario] When I recruit users for tests that I need to run...I need to identify which users I have reached out to and which ones I have selected. I would like to to a Find All (at once) and some how indicate in a column with an "x". Any ideas?
