As we make more use of Monday and start to automate/simplify more of our processes, it would be really helpful to be able to add a column to the Portfolio to pull a date field. The user case would be to have visibility on the portfolio of when the date is going to happen to be able to invoice on time. I reached out to Support and they showed me the Mirror functionality but this pulls based on the column name. It then shows all the dates. What we would need is to look up a specific item/task name on each board and then show just that Target Date.
Mirror fields can point to any data field on a different board that you want them to and you can have as many as you want. If it is just a static pull you can use a basic mirror function. If it needs to be dynamic then look into the MATCH feature. It’s a beta tool I use to much success.
