Email templates: Increase the limit of columns for inline tabular reports (currently 5)

We are building a Digital ‘Business Review’ that is the e-mail template comprising of several embedded reports sent via JO. With the limit of 5 columns we have our hands tied a bit as our aim is to make the email as informative and accessible as possible. We’d like that the customer opening the email has everything in front of them without a need to open attachments. With 5 columns it’s hard to achieve.
