In customer reports, we have an option of 'fx calculation'. It would be really helpful if Aha! enables to display its values in different forms like progress bar or just a number. Currently, the portal shows a number only.
Thanks for the idea!
We will continue to monitor this idea for community feedback. In the interim, although it is not based on a list report calculation specifically as you noted, you can now enable progress on your records and display as a progress bar in list reports.
