Good idea, but in the meantime you could create a template column that joins your multiple columns together. I’d recommend separating each item in the template with an obscure character, like a pipe ‘|’. Ideally, if your columns had values that were the same length, then it would work perfectly, but you could always do the joining in google sheets and add padding to each column while joining.
This may work for the most part:
‘Value aaa | Value bbb | Value ccc’
‘Value ddddd | Value ee | Value fffffff’
This would be better, where each value is spaced equally between pipes:
'Value aaa | Value bbb | Value ccc ’
'Value ddddd | Value ee | Value fffffff ’
