Hi Andy, Yeah, this is a golden oldie, but can't seem to find my remember-to-avoid-multi-check-boxes link, so in short I would recommend you:
split that column into six separate check boxes
use either bulk updates or our "https://store.atappstore.com/product/excel-updater/" Excel Updater solution to then populate the appropriate boxes
rename the old field to _OLD
add a calculated parameter with the old field name
write a formula in that calculated parameter that concatenates the six separate check boxes
confirm that the latter allows any reports that referred to the old field name "still work"
drop the old field name
With the above in place, welcome to planet Independent Checkbox, where it is legal, easy and fun to then:
Filter by any one (or combination) of the six
View each of the six as their own column in a report, off their respective independent fields
Edit the above in list mode by simply clicking into the respective column
View the combination of the six in a single column in a report using the new calculated parameter
Group by any one of the six
Group by the various (well ordered, thanks to the formula) combinations via the calculated parameter
Entertain making some charts using any of the six
