Interface option - multiple values recorded in one row and column

[StephenJPSheehan]

Hello,

I'm not sure how possible this is in Alteryx, but my ideal solution would be to have an interface option where a user can select a choice of multiple values (either a checkbox or possibly drop down option) which would then update a brand new column made up of multiple selections.

For instance, using the List Box as an example, the user has a choice of selecting numbers 1 through 10. All numbers selected by the user would then be added to a single field in one row separated by commas (e.g. if a user selected 1, 8 and 9 the resulting column would be 1,8,9)

I've been looking at the various Interface options in Designer and haven't been able to solve the problem using them. Appreciate any advice or anything I may have missed!

I'm sure I've misunderstood, but this might be a starting point,
