This seems to be expressed in the final comment on this thread: Custom Field Limitation - #8 by Danielle_Yockman Not sure why it was closed, as I agree with the feedback and find it perfectly valid. I’m not sure why advising people to shove more info into an unstructure text field (Description) is seen as the final word.
Maybe our team needs a more flexible tool than Asana, or should just make our own app/database to avoid limitations like this. Staying with Asana and having them increase the limit would certainly be preferred at this point though!
