Inserting New Line Character in Worksheet Strings

Worksheets allow you to have formulas that concatenate strings and create a new string to display to the users. However, there is no way to include a "new line" character so that the display separates items by new line. Below is the use case we have today.

Use Case:

We created a custom table to track specific team’s activities in support of an Idea’s vetting an approval, and overall cost estimate. In the Idea level, we want to provide a summary of the costs by team (in the custom table, a team can create multiple rows each with its own cost estimate). The way we are handling this now, is in the Worksheet I am creating a row for each team and doing a sum calculation from the custom table for all rows identified for this team. Since we expect to have about 30+ teams in the organization, this worksheet will be very long. To avoid that, I am trying to only show the cost for those teams that are impacted in the custom table (typically should be 1 to 5 at the most). I can do it now in a string but it shows the information in one line and hard to read, so would be helpful if I can break it up and have one line per team. Below are images of the custom table and the summary worksheet we have so far. Note that I only include 5 of the teams so far, but expect to include many more soon.
